It was a dorky little afternoon project to see what it would look like, not an attempt at a commercial product- that should be pretty obvious from the descriptions I've provided below. People were creating volumetric displays long before USC and Sony, too. Piston-mirror technology has been around since the 60's, for instance.

As for breaking out the bear, this an American euphemism I am not familiar with.

Troll-block, engaged.

:) It is a piece of 1/8" thick acrylic, about 6" square, and covered with white paper on the upward-facing surface. It is mounted at a 45 degree angle to a swivel chair bearing assembly, which in turn, is mounted to my old Tek oscilloscope (was used in some prior experiments). It's so crude that we worried about it flying apart at any moment. But then curiosity and danger often walk hand in hand ;)

I was bored out of my mind when I was watching that. What were you trying to make?

[Donenotperfect]

The cure for boredom is curiosity. Entertaining the incurious did not factor into my decision to share the video.

WOW! I am definetly going to try this! Only I think that I am going to use some of my 20K scanning Galvonometers that I have to make some shapes instead of just the random music patterns! Great idea btw.

[Donenotperfect]

Oh yeah, that is totally the way to go- fast galvos and if you can rig a blanking channel that is synched with the rotation of the surface, then you can really do some cool stuff. Would love to see vids of it! :)

well ...you was almost on to something...but it been done already by usc/sony...but lets break out the bear and enjoy ur sh......t

And where is the 3D?

[304Stephen]

More like laser show than display, since it hardly displays anything at will.

[hullmees11]

that is very good idea . i have an question . does light goes trough laser? ´is there a laser's what can stop other holographic light or something?

[Level84]

that shit sucks

[terorvlad]

cool idea

[ayeyen]

Is that "she blinded me with science?"

Brilliant.

did you try spinning it faster ? it would look much better :P we did one simillar project :P and we did spin it faster ... and ... yes it dissintegrated in about 10 seconds :)) but it looks better at higher rpm, now we're triyng out a projector thing :) to synchronize it with a projector and get one of those neat volumetric displays ... anyways NICE JOB THERE !!!

wow for one you dont gotta be a jerk. for 2 your obviously jealous. for three whats it to you even if he was a "nerd". and for 4 you prolly just go around calling others names to make you feel better about yourself....
