iphone/ipad painting game

hi guys! The game will have the user to paint in simple black color. There will be a rubber to delete and one pencil to draw. the paintings are limited to the stage. The user will paint like on a blank paper. So there will be only one fixed stage. There will be gravity, and collusion physics involved. # the application will have to be ready to publish through the appstore # the application needs a function to screenshot (and save on ipod/phone and publish to facebook. - only if it would not boost the price too much) #needs to work for iphone and ipad in fullscreen #i provide graphical elements i will tell you more via private messaging, so i wont receive too many copy pasted texts. thanks for understanding! daniel
