Flip-book style animation previewer for the iPhone and iPod Touch.
Flipper is a utility for animators working with the iPhone. Great for previewing small sprite animations on the retina display, or for seeing how much memory a larger animation will use.
How it works:
You upload a sequence of PNG images to a public web server, point The Flipper to the images, and submit!
It will even show you how much memory is being used in total and for each frame of the animation, and will warn you if you're exceeding the recommended maximum for the device.
