After seen a lot of videos of XSI and lagoa creating a realistic sand, I tried to do something similar with Thinking Particles.
The approach is totally diferent, and is not a real elastic simulation with real cohesion force between particles. It will not work for sand splashing with other surface but I think can work well for sand dissolution in the air. Also breaks the over used look of pflow+deflector+wind+krakatoa, pushing it a little further. Simulation times are quite fast (less than 10 minutes for 300 frames simulation) , I have some ideas to improve it a little more, so maybe I will redo the video with a new setup.
