One of my co-workers, Jiayi Chong, wrote his first iPhone app called, “Fish!”. It’s a simple little game where you touch the screen to drop food, which attracts the fish, and you try to get the fish to collect gold coins. But the coolest part about it is that he implemented a full SPH solver to simulate the water. What does SPH stand for? I think it’s either Smoothed Particle Hydrodynamics, the mass-conserving mesh-free Lagrangian method, or Silly Putty Heuristics. Another cool feature is that when you complete a level, it creates a graphical interpretation of what you did. It’s $1.99 on the iTunes Store. Check it out!

    That’s pretty sweet how you can tilt the phone and the water just shifts and you keep playing. Congrats to your friend. I hope he makes some good money for his time.

    Yeah, he’s pretty excited about getting his first app online. Unfortunately, the market for SPH fluid solvers isn’t so hot right now. But he’s got a number of other ideas.
