Yep, kind of makes your signature line hold true.

I was googlin around earlier for fiber optics and saw a site advertising "side glow" fiber. It appeared to light up like a neon tube.

My thought. It it would receive light into the edge ? If so then maybe the more of less exposed would change the intinsity of light at the end? Make it work backwards.

Anyone played with this stuff?

they talk about a very bright like to make it glow, so maybe it would not work...

I have not played with optics much. What would happen it a glass rod had a flat side?
