Honestly I'm not seeing what's different. I'm working on a hybrid canvas/html5 feature app right now. A good portion of the API (p5js.org/reference) feels, well, typical.

I don't want to discredit the project, it does look nice. You're point about beta is good.

In fairness, this appears to be targeted towards non-programmers, and having been deep in UI for years I may be missing the simplicity sake.

Also, I had no interest in slamming them for a temp broken browser context... rather I'm trying to understand what makes this awesome. In years of browser UIE I hadn't heard of http://processingjs.org/.
