FAQ:

 - What is this?
   It's a port of info-beamer in pure javascript. The port was created using emscripten. 
   It displays a sample info-beamer node called shader.

 - Is it a full port of info-beamer?
   No. Only the minimum required to show this demo. It doesn't support fonts, jpg images, 
   videos, vnc. It cannot update code on the fly. There is no way to interact with a 
   running node. So it's mostly a toy right now. But hey: It's C progam with an embedded
   Lua interpreter running inside javascript displaying some shader modified image in WebGL.

 - Is the source code available?
   No.
