Math for Game Developers - Backstabs and Dot Products

This week I've released the coolest entry in the MFGD series yet:

Learning dot products by implementing a backstab mechanic a la TF2. There's also a few videos on vector manipulation since I posted last, you can view them from the MFGD Youtube playlist: http://www.youtube.com/playlist?list=PLW3Zl3wyJwWOpdhYedlD-yCB7WQoHf-My&feature=view_all

Enjoy!
