Not a laser, but lots of cool photons...

I want one!

I wonder if Swami or SaltyRobot could replicate the physics of a double pendulum in LSX... hmmmm... think of the possibilities ;)

i love this project.. but i'm just not inspired by the patterns it generates. i think... (makes the noise of a lightbulb tuning on).. maybe.. hmmm

It could be the never-ending-laser-show.

I love the patterns it creates, but I'm thinking it could use some more colors. ;)

Are there any phosphors that glow different colors based on different excitation lines. Like 405 gives the green and 445 gives a red or such?

Well, there are materials that glow in blue, orange, white, green and yellow that have long persistence. Take a look at the wikipedia phosphor type table. It doesn't list what is the key excitement method though, but practically speaking, I doubt you would want to combine stuff like an electron gun out in the open next to a UV laser so that you could excite different materials to produce separate colors. That said, this page

I have considered painting a wall with a tight grid or bands of various colors of GITD paint and using 405 to excite them for a multi-colored GITD painting - essentially reproducing the approach used for color CRT-based TV sets. I haven't gotten that ambitious yet, though. In addition, I'm concerned that the pixelation and shorter lived colors will result in a less than impressive result. (e.g. the red glow in the dark paint glows at 10% of the brightness of the yellow-green stuff).

In the end, would this be the right tool for the job or would video technology be easier, better, and cheaper? It's like trying to do graphics with a moving scan head. Its just silly to do that to draw simple figures as opposed to CGI rendering and a video projector, right?!? <cough cough> ;)
