bullet.js - Javascript Ragdoll Physics

I ported more classes from JBullet to Javascript Physics engine bullet.js, wrote some new and assembled a new canvas demo showing javascript ragdoll physics: Click. Now almost all classes from JBullet are ported, except some for vehicle physics. The size of bullet.js is now about 330kB. The demo shows on my pc using Chrome ca. 40fps. The current drawing (software 3d using canvas) is not very performant, so soon there will be bullet.js+WebGl demos.
