I've been thinking of building such a thing myself but I'm not sure what I like for the cutting.
Just regular saw for metal, nothing special. But carefully, trying to keep the saw along the surface. No torch, no cracking...

One more thing. I was thinking before I could make similar device from parallel plastic (like CD cover, photo frame etc). This will not work! Light goes through such parallel surfaces without exiting out (the waveguide). You will see illuminated areas only at the LEDs and the edges. Something is needed to make the light go out of the waveguide. LightWedge technology uses wedge to break waveguide effect. may be something else can be also done (like some transparent irregularities on the surface).
