Very cool (note that you can place the light and drag it's direction)!
One thing I noticed is that this visualizes how dangerous laser light can be.
A lot of DIY projects these days use lasers (SLA printers, Laser cutters). You can't warn people enough about the risks when working with lasers.
This app shows how laser light bounces around in ways you don't expect.

Floating point textures seem to be a particular weak point with WebGL on mobile devices. I don't understand why, though, as the devices I looked at actually support them with native apps (they're in the ES3 spec), but not with WebGL.

Not necessarily. We don't know what the index of refraction is on the prism on the album cover, nor even if the whole prism has a constant refraction index, or even if it's solid.
But yes, the artist probably didn't depict it based on science.

My mobile devices do OpenGL ES 3.0 and 3.1, none of them runs the demo.

Both in regular Chrome and in Canary. Why?
