Laser Frame

Laser Frame was an iteration on Laser Paint, albeit a much lower tech version. One day while watching TV in my living room, I was playing with the blue laser that I used for the Laser Paint project, and inadvertently passed the beam over my remote control. When I did that, however, I noticed something amazing -- the buttons on the remote started glowing brightly, even when I turned the laser off! After some time of marveling at this phenomenon and giggling as I repeatedly passed the laser over the buttons, I did some research to figure out what was happening. It turned out that the buttons on the remote were glow-in-the-dark buttons, and glow-in-the-dark (phosphorescent) material responds most strongly to light in the blue part of the spectrum. We normally hold glow-in-the-dark toys up to lamps to "charge" them up, but the toys are mostly just absorbing the blue part of the white light that gets emitted from the lamp. Since a blue laser is highly concentrated blue light, it charges the material up really quickly and makes its really bright.

So, the natural next step was to get a large sheet of glow-in-the-dark fabric, put it in a fancy wooden frame, and hang it on my wall. More laser-based drawing fun!
