Hi All, I was wondering whether anyone has managed to wrap John Resig's processing.js library in Google Web Toolkit (maybe in combination with GWT Canvas) or knows of any resources or sample code out on the web.

I've looked around Stack Overflow for an answer to this, but nowhere seems to give the correct answer or direction...

The next obstacle is working out how to ex...
