The demo does not work

[mattes3]

The README.md file links to a demo on glslb.in. That demo does not run because the server returns an error 500 and says:

Missing package version (glsl-square-frame)

This issue still exists, except now it's a Heroku thing rather than a 500 HTTP error.

I'd love to see the demo!
