A really cool (slightly burned) 3D glitter effect inside the plexiglass!

Lately I have been messing around with making some edge lit acrylic signs and I have been sandblasting them to get a frosted look on the glass. Unfortunately my air compressor is small and doesn't produce the real frosty look I am going for. The most recent sign I made is a prototype for the marketing department where I work (TriQuint Semiconductor). For this one I thought I would take it to work and see if I could use our laser marking machine to etch some really sharp lettering into the glass. I guess I need to experiment a little and find out how to make it work right. The good thing is, I didn't totally destroy the sign and it gave me a few ideas to experiment with.
They are relatively easy to make so maybe I will attempt to do a short tutorial or maybe even an instructable. The instructables I found for making them are not very well done, but they do show the basic concept.
Below are some pictures of this sign and another I made for a friend's band.
