Internal Refraction

[loop]

I'm currently building a new mousemat out of clear 2mm thick acrylic, I have embedded in a recess in the middle of the mouse mat some blue neon string, unfortunately rather than just shining out allover generally, the majority of the light gets stuck inside of the acrylic (internal refraction) and can only be seen when it leaves right at the edge of the mat. What I want to know is there any easy way I can stop this from happening so that the light from the neon string just passes out to the surrounding area happily.

I'd think thats a pretty cool effect! what i would do is cover the portion above the string with something, so you cant see the string at all, and all the edges will be lit up and look funkeh!

I suspect that the only way you'll be able to do this easily is frost the surface, so that it's irregular. Unfortunately, that doesn't look so good.

The other alternative would be to find a material with a change in refractive index. I suspect this will be expensive!
