 Thank you very much There's mech over there somewhere Anyway, so I'm giving this talk because John to ask me to do it Which is the start of so many good stories around emf camp. So Yeah, it's gonna be fun. So Basically, I got asked to describe what the demo scene is and give you a good primer for it Which I thought was gonna be really easy because I just prattle on for half an hour about demo scene stuff And then I realized nobody has a good concise answer to actually what is the demo scene So I kind of went on discord a little bit and crowdsource the answer and I got a couple of good ones Something something Eurovision, but with more nerds and they're singing Which I think is wholly inaccurate because British people do sometimes win things at demo scene competitions So I worked for another one Screen saver Olympics Which is pretty good so the demo scene itself is more of a celebration of digital arts things that people have made and kind of Real-time demos are a big part of that There's also graphics pictures different platforms music animations Lots of stuff essentially we we have competitions around photography Size-coded demos and all sorts of stuff in fact We even have here like a young person's competition in field effects So we're trying to attach a new audience So demos which is essentially where the demo scene got its name are essentially real-time generated programs there They can be size-limited or unlimited and essentially it's just maths making cool graphics and sounds So it's generally a non-interactive A program You load it up. You'll always get the same graphics and sound come out Everything is generated by the algorithm sometimes I say We started off just having Unlimited sizes and then it got down to limiting to 64 kilobytes and how much you can pack into 64 kilobytes And there's also eight kilobytes four kilobytes And then we went down to something stupid and got 256 bite demos, which is quite fun Anyway, so I will show you a Demo do we have audio? Sorry Missed the audio on that one So ah So that entire demo Was generated in four kilobytes of data all the audio all the video and the bootloader pretty impressive The bit into the origins of the demo scene So we started sort of like in the early 80s, which was a bit before but it was Originally when people were copying games and Piracy a lot of the time they would stick their own little Nugget in the front of the game. So whenever you load the games up, you'd say something like crystal cracked or raisin Or whatever the group was So very much it was born out of computer swap me so people would go to swap sort of like games This is no longer the case. We no longer taken software piracy at least most of us and We've evolved a lot over 40 years So originally it was more North European scene Now we're very kind of multinational we have needs all over the world from Australia, Japan and wherever So yeah, essentially The way the demo scene grew a lot was we integrated with a lot of gaming lands So there's a land party in Finland called assembly which happens every year that happens about 5000 people so it grew originally that started as a demo party It's now grown to 5,000 people it's mostly gaming and it's one of the biggest gaming lands in the world They still do a lot of demo scene content But yeah, so now we're completely separate from the gaming scene We've basically become our own thing. We have basically lots of different kinds of parties and competitions and You know, let's say a lot of it is still size code the size coding limitation actually came from Software piracy because essentially the game on the disk or the tape would pretty much knock up to exactly how much You could fit onto that tape so fitting any extra bits in front of it for a demo was really really hard to do so it was It was kind of like a lot of Technical skill went into that probably Almost as much technical skill went into just getting the demo onto the front of the game that went into the game itself Which was kind of cool in some of them But now we're completely separate We have over 50 parties a year pre-covid The best the biggest ones up to a thousand and Since COVID happened actually it's been a real change for a demo scene because it's not Necessarily just based around going to parties and and kind of like meeting up with people and showing your demos at parties You can basically sit at home now and code up a demo and then find a party online Because all of our parties moved online and just show it there So a lot more parties sprung up around kind of like this kind of like online scene Which has pushed us more to towards that So we've started having more in-person parties, but we're still having a lot of online parties There's not quite as many in-person parties going at the moment, but hopefully that's gonna ramp up again soon And we're gonna be going But yeah, I'd like to say with a lot of the online Dermaparties, we're starting to attract a new younger audience because before a lot of it was old men like me And now we're starting to attract younger audience more diverse audience a lot of Women and people minorities are getting involved, which is something we really want to push as well You know, we we want the scene to be as inclusive and open as possible to everyone We're very open people. We kind of try to pass on as much Information as we can where we can Yeah Yeah So some of the demo competitions we have I say it's like old school We still use Amiga's and Commodore 64's Atari's BBC Micro's pretty much everything You can code on you can code a demo on and if you can code a demo on you can put it into a demo party and You know Really appreciate kind of like all different kinds of demos don't have to be big flashy graphics Or audio it can be kind of like just a few pictures and if it's your first demo Like everyone still appreciate like the effort people put in Amiga is actually still one of the biggest platforms we use has more demos released for it every year, which is Really cool Let's say So it's limited 64 kilobyte for a bit. There's a lot going on 256 kilobyte now and Also, we have the tick 80 which is a what's referred to as a fantasy console And what fantasy console is it never actually got made but someone's just invented a console that they would make and it's sort of a 8-bit machine with Very limited kind of like graphics and audio capability and the things that people coming out with for that are really a really good One of the newer inventions of the demo scene is competitive coding as well, so Essentially, we have two forms of competitive coding at the moment. We have the shader showdown Which is happening on here later tonight two participants on stage 25 minutes each and They have to code in GLSL the best shader they can possibly find And I do have one Sorry guys So this was coded in 25 minutes on stage revision It's basically a shader in GSL. Everything is done in maths And Essentially, it's done using what's called a ray marcher So ray marches are essentially You can kind of set up objects within the screen space and set up a camera and you send out rays from the camera So every single pixel of this scene There's a camera a camera. They're going like right. Okay. What do I need to display at this pixel? But it fires rays until it finds something that it hits or it doesn't hit and then it returns a default color Again that was entirely coded in 25 minutes on the stage, which is really cool Again, that's gonna be on tonight as well in here, I think nine o'clock, but I'll have to check that So the other which is a newer invention, which is the bite battle Which we're also gonna show here tonight So as I said the tick 80 is a thick is fantasy console with 16 colors 240 by 136 pixels and you basically have to code The best kind of like scene you can in that and that's more of a per pixel coding rather than a general algorithm code coding but some of the stuff that people have created in that is Really amazing And yeah, I think that's gonna be on after the show show then tonight, which should be at nine. I think So I will check So the demo scene has actually now been accepted by the UNESCO World Heritage as a Intangible cultural heritage So essentially in currently in Denmark Netherlands Poland, Switzerland, Portugal, Finland, Germany and France Unfortunately, not the UK yet because the UK UNESCO branch Doesn't seem to like us very much But there's a whole story behind that which I'm not gonna go into at the moment, but it's very long and arduous But what this does mean is that we have the same recognition as a lot of other kind of like cultures and sort of like heritage sites and it helps us get recognition helps us get sponsorships and Kind of helps us get more kind of like Brand out there people are interested in it and it's not just us geeky 40 year old to plus who who are now doing it Because of this cultural heritage we were able to spread to a much wider audience So Yeah So in the field effects tent this time if you go down there, we're running some demo competitions registering at That woohoo dot field effects dot party So if you need to upload an entry Doesn't have to be there's a bunch of different competitions So you can just kind of select your competition you want to go into I would do that now So just fill in the form if you come to the field effects tent We'll give you a show of exactly what we're doing there The deadline is tomorrow though, so it might be a bit of a rush But yeah, if you register on there and then tomorrow evening we're gonna be running the demo competitions in the field effects tent You can come there and you can vote on which one you like the best So you can go to when you go to the demo competitions, which is starting at seven o'clock tomorrow in the field effects tent You can log on to the woohoo app and then Vote for whichever one you feel so when voting a lot of people have a fear of like I don't understand this I can't vote for it or I would not inform Don't be afraid of that like people just just vote for whichever you think is the best and you know That's what that's how we get like participation in that and then you can be a part of selecting the best demos that we have So finally, I'd like to give some demo scene memes We have Kevin Kevin was a character from a space bigs demo It seems to have grown outside that if you see him called a dentist Evil bot so evil bot starts in 2016 stood for election revision and won the president of the demo scene 2016 seemed to be a very bad year for elections and voting. So yeah And Amiga so a demo competitions people tend to shout Amiga lots if you hear people shouting Amiga Don't be afraid. Just ignore them and walk Yeah Thanks guys So, yeah, finally Come by the field effects 10. I Can pick up a vote key there? Can find all our schedule info on field effects party and register on the woohoo app and then You can come and vote come and watch all the demos will be there from 7 o'clock tomorrow Showing all the competitions and everything and everyone's more than welcome to just drop by come hang out watch some cool demos and Watch everyone. You think it's the best So thank you very much
