Mibbu – Framework Javascript para Games | Jaydson
I had the pleasure of personally meeting Michal Budzynski at BrazilJS . Among many excellent lectures, Michal’s really opened the minds of many people.

Demos below! As a sort-of reverse birthday present I’ve decided to release one of my largest projects, in recent memory. This is the project that I’ve been alluding to for quite some time now : I’ve ported the Processing visualization language to JavaScript, using the Canvas element . I’ve been working on this project, off-and-on now, for the past 7 months – it’s been a fun, and quite rewarding, challenge. The full scope of the project can be broken down into two portions:
