Day 9: Quaternions

Today was horribly frustrating...to optimize the rotations of the engine, which are quite expensive, i decided to pass to quaternions.

I already used them in the past, but somehow today i passed my day trying to make things work.

I finally fixed everything after i don't know how many hours, and now my camera works perfectly, tomorrow i'll try the same thing with the other game objects, and i hope it to be quicker than today...

I also played around a little with the engine, and made a few other cool looking effect with lots of cubes
