Crowd Blossom app for iPhone and iPad
A simple gathering simulation.
A random 2d isometric world will be procedurally generated entirely based on some rules on the fly. The crowd of 8192 sprites will move to the selected position along the field of shortest paths and then restart with random initial velocity after that. These sprites may collide elastically with the hills as particles. The frame rate of the simulation is expected to be about 60FPS(6 ticks of the top ruler) if vsync is enabled.
