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

It sounds like a Danny Rozin piece

These are close but it was definitely horizontal these are vertical. Thank you for the links!!

I have been thinking about this for some time: cylinders each attached to a motor. The glossy end of the cylinders is cut at an angle. The rotation of each cylinder dictates from which direction light is reflected.
