Parapara Animation is a neat little site for creating custom animations that I just found out about from Richard Byrne's excellent blog. Users of stop motion animation will feel right at home as a user draws a picture then clicks on the + button to add another frame. When that happens an outline of the previous frame is seen on the new frame to make the animation flow seamlessly. A finished product can then be shared via URL or QR code.
I highly recommend checking out Parapara Animation by clicking here!!!
