There is an artist (at least) that uses arrays of motorized parts to create a similar effect <a href="https://www.youtube.com/watch?v=kV8v2GKC8WA" rel="nofollow">https://www.youtube.com/watch?v=kV8v2GKC8WA</a> mesmerizing
What an absolutely amazing piece of work, and even more incredible that it worked the first time. If I had to do something like that it would take me at least three tries to get it to work and quite possibly more than three. Math, 3D printing, love, what's not to like :)<p>And congratulations!
This is future of the street art. Mount it using liquid nails to some place that is hard to access and point it somewhere where lots of people will see it during rush hour.<p>Eg.: You can install it in such way that parliament building will get defaced every day during lunch hours by mounting on near building or tall lamp post. Or maybe put it on your own roof, that way nobody can remove it :-)
Has anyone seen the mirror array that was built with ~2"X2"stainless steel mirrors that are attached to a sheet of blue spring steel that was laser cut as a compliant mechanism for each mirror so when an offset wheel on a threaded bolt behind the mirror is turned it progressively tilts the mirror from a minimal angle to a maximum angle? Each bolt was then driven using a single stepper motor(one mirror adjustment motor for the whole array, kind of a budget build, instead of one motor per mirror)on a belt driven x-y frame. The mirror array was positioned horizontally 2' off the floor of a museum with works of art, a camera is then pointed at an angle near eyelevel probably 20' away from the array. Then you choose an art work and the mirrors are rotated through their angles and when that pixel(mirror) reflects the color back to the camera that matches the art work you chose it stops moves to the next mirror and then repeats until there is a full image made of reflected light. Obviously the final image is pixelated but roughly resembles the original work. I saw this years ago and can no longer find any of it online. I've tried every search combination I could think of. Some of these details might be wrong but I'm just going off memory here. Pls help
Bears a striking resemblance to the James Webb Space Telescope<p><a href="https://en.wikipedia.org/wiki/James_Webb_Space_Telescope" rel="nofollow">https://en.wikipedia.org/wiki/James_Webb_Space_Telescope</a>
Reminds me of Mitsuba 2; see Caustic Design at about 3 mins into the first video: <a href="http://rgl.epfl.ch/publications/NimierDavidVicini2019Mitsuba2" rel="nofollow">http://rgl.epfl.ch/publications/NimierDavidVicini2019Mitsuba...</a>
I'm wondering if a similar effect couldn't be done using a continuous surface and just silvering it. I saw something similar done with refraction but can't remember the URL now. 3D printers definitely have higher resolution than mirrors of this size.
This is very cool. Perhaps I'll similarly do a writeup of my nerdy marriage trick -- I created custom 3D chocolate bars with our faces on them to hand out to guests. It required a ton of iteration and a lot of chocolate work (which is really hard!), but was really special in the end.
I wonder if rather than "additive" you could do similar with "subtractive" fabrication. Take a wooden board and cnc mill and cut circles on the surface at the appropriate orientations.
Someone else's work that alters light transmission (instead of reflection): <a href="https://mattferraro.dev/posts/caustics-engineering" rel="nofollow">https://mattferraro.dev/posts/caustics-engineering</a>
Now how could we achieve the same thing with just origami?

Did you try sinking any ships with this?

Cool! Makes a nice object to hang on the wall too!<p>I wonder if there's any types of filament that could be used to print a mirror-like surface good enough to work ?
Very cool.<p>In a less-artistic application, you could use this idea to print multiple sections that could be assembled to make a large pseudo-parabolic mirror for a solar concentrator. You wouldn't get telescope-quality imaging, certainly, but if all you needed was to concentrate a lot of light on a small space (for a steam generator, say) it should work fine.<p>Congrats on the upcoming wedding!
At a risk of spoiling a startup idea, I'd love a set of motorized mirrors I could put on a roof of a house on the other side of the street from me, that would send sunlight to the eastern side of my flat during the afternoon :).
This reminds me of company called Leva.<p>Check out this project

> that could just bring this idea into existence from nothing but a bit of code and some basic principles of physics.<p>You're putting yourself down here. But congrats on the proposal!
I might be getting old but this is the sort of magic by technology I would like to see more of in the world instead of using tech to try putting people into fake worlds in some metaverse.
