when i was driving to my cabin i was thinking that there should be a good skiing iphone app. I was thinking i could be based off of ski stunt simulator except be more realistic and have rails. As far as controls there would be four arrows you could press two for spins and two for flips and combinations would allow for corks/rodeos. and to make the skier move forward you would slant the iphone down the hill more extreme to go faster and less extreme to slow down. Somebody who knows how should make this. any input?
