Kirk K. writes about "Bliss Lights", a fancy lighting projector that sprays a moving pattern of lights all over:
I saw these guys at a lighting conference in Vegas this year. They make these little laser emitters that project these little star-like fairy lights everywhere. A fascinating product. I think they have YouTube videos of these things in action. Really neat!
And lo, there were videos on YouTube.
I guess the diffuser on the front of these things steps down the laser light enough that it's safe for the eye, because there's certainly no way you'd be able to avoid catching some in the retina when these things start moving.
