Hello, dear KSP devs and fans! I would like to offer my help to build a mobile tribute to KSP. I'm good at physics and realtime calculations under iOS. But I'm totally noob in 3D things. So let me know if there is someone who wants that too. I could build a concept (with almost no graphics ). Just in case, concerning CPU. Modern mobile processors have a lot of calculation power. First generation iPad is capable of calculating hundreds of thousands differential equations per second on it's SIMD extension. You could literally hear it in good realtime audio equalizing algorithms. So CPU power is not a problem. Peace!
