    I am trying to make an application as proof of concept. I have an image, with which I want to fill the screen. When the user clicks somewhere, I want the image to be distorted in that spot, like if it was on a net of some short (that spot of the image going forwards and backwards).

    Does anyone have any idea on how to make this possible?

    For simple animations, CGAffineTransform and a bit of matrix algebra should do the trick. Depending on the sort of thing you're going for, OpenGL ES might be a better option though.
