Chrysaora

This experiment evolved from the previously submitted Jellyfish experiment. In addition to the animation and shading from the previous experiment, this one features: 1. Dynamically simulated skeletons (spring chains) 2. Partial server-side simulation and synchronization with WebSocket (node.js and socket.io) 3. Camera-facing particle system and volumetric light effect. 4. More sophisticated lighting, model and simulation controls. 5. Improved animation and shading. 6. Implemented Vladimir Vuki?evi?'s mjs matrix library Some of the shaders might be too complex to compile on some graphic cards. Please let me know if you get shader compilation errors. Any other comments or questions are welcome :)
