 More plug plates. So basically these plug plates were originally used on SDSS and instead of throwing away we're upcycling them into a way to represent redshift to those who are visually impaired. Each one of these holes has a value of redshift because each one of them is associated with a star, galaxy, and a quasar. Each one of these pulls triggers a sound associated with that redshift value. So as you can see if you pull it here you have a lower sound, it's pretty quiet, and then this one won't pull as far. Galaxy has a less redshift. It has a higher tone. And so this is our first integration of this upcycling of this plate. It's an extension of the Yerkes Upreach Program and kind of keep it moving and this is what we've done in a couple months. Where will this be installed? So basically we're just trying to reach out to schools. I think that's our end goal and make it so it's easily transportable. Do you have the tactile telescope, do we? I think it's over at the poster. Yeah, so if you press down on each of these try to order them by how easy it is to push down on it from easiest to hardest. I'm going to go with this one's the easiest because the key fell out. Okay, that one's easiest. Then this one, then this one. Then this one, then this one. Amazing. Good, you got them all right. The constellation one. You good? Okay. So one of the things that we've learned with teaching astronomy to blind and visually impaired students like myself is that you have to teach a lot of really basic concepts before you can move on to the more advanced things. So one of the first ones is when we're observing we look at the sky and it's a dome. Well, how do you explain that to a blind person? You give them an umbrella, which seems perfectly appropriate for being in Seattle, so I'm going to get seven years for this, but we're looking at the outside of the umbrella right now, which has the constellations on it. And these tags here are brailed representations of the RA. So you can move it around to show how the sky rotates and actually you can measure where you are with these brailed buttons here. And then along the outside here, you have just the constellation. So you can show, you know, how the stars connect and I don't think they look like anything that anyone says they do. So in the inside here, we've got buttons to represent the stars and we've messed around with ideas of having them up here at, you know, different sizes or different shapes, but it's just got kind of convoluted and confusing. So just to demonstrate the stars themselves, we went with kind of this basic pattern so that you can reach up and you're literally putting yourself at the center of the dome and then you're able to reach in and touch the stars literally. So this allows a lot of people with blindness or low vision or just people who are kinesthetic learners to have a better concept of what the sky looks like as a dome. That's amazing, it's an awesome dome. Thank you. It's so portable too, it's brilliant. Okay, that was super cool. That tactile astronomy, that visually impaired astronomy thing is super, super cool. And it's really exciting to see the work continue and some new innovations.
