Totally not what this post is about, but CONNIE ROCKS!
Check out the link that Connie sent – Lexan light art in the form of light sources shining though a fire-tempered Lexan diffuser thingus. Yes, thingus, it’s a proficient technical term. Of COURSE though, after seeing these shots, I went and looked up the refractive indices for Lexan, of course I did. It’s somewhere between 1.4 and 1.56.
If you decide to recreate something like this for your own personal enjoyment, make sure that YOU DO NOT BREATHE BURNING LEXAN. Its smoke is highly, highly toxic.
Thanks, Recyclart! What a cool website you have!
