OpenJSCad is an awesome idea! I just found this after checking out CAD software for 3D printing and OpenSCAD for the first time. My immediate thought was "this would be so cool for WebGL".
Apparently openjscad.org is the current version / better front end using the fork from [
github.com]
It even works somewhat with my android smartphone with touch. But the camera controls are aweful.
I was able to simply drag and drop .scad files and use them!
Really nice for online collaboration, sharing builds via links etc. Ideally you'd want to link to a ".jscad" files on github with this and make them parameterizable. Would be great to host this on a webserver on your Beagleboard to input and plan a print.
