I made color changing glasses!
I found an old, broken monitor by a dumpster and I desired to play around with the polarizer. These glasses rely on two polarizing lenses in a 3D printed frame that allows their phase angle to be varied, resulting in different colors! My initial plan was to make variable darkness glasses, but the polarizer was very diffuse and hard to see through. To solve this, I ended up adding clear masking tape to the lenses. It make them much easier to see through, but it came with the surprise of changing color instead of brightness! I decided to pivot and ended up with these. The effect is most pronounced when one side is very bright, and the mechanism for rotating the lenses is pretty chunky, but I'm happy with it for a prototype! I could see a similar technique being used for a camera or projector lenses in order to vary color. Who knows!
