I've updated the jsGameSoup project with a couple of new demos showing how to integrate it with some 3rd party libraries that are useful for making video games.
The first demo shows how to integrate the sylvester.js library. This is a great little single-file Javascript library that covers the basic vector and matrix math nicely. Check out the attractors demo, and don't forget to view source!
The second demo was created by Nick Lowe and it shows off the Box2d.js physics engine integrated with jsGameSoup. Check it out! I'm really happy to have such a robust and popular 2d physics engine working along side jsGameSoup in the browser. Great stuff!
