New Video and some info

Hello!

Now the renderer and simulator are both multi-threaded so I can take advantage of my old PC with two 3.0 Ghz processors. Here is a new video and some info about it:

- Particle Count: 65000
- SPH Integrator Type: Leap Frog
- Time Step: Fixed 0.001s
- Simulation Time: 5 hours approx. (yes! I know it´s slow, I´m workin on it!) :O)
- Render Time: average of 30 seconds per frame at 640x480

I´m working on some optimizations for the simulator so I hope I can speed up the simulation soon.

See you!
