Here is a look at the frame by frame or composition interface of the iPad app, DoInk.
Below is the quick test of the Doink animation app for the iPad, and youTube I don’t think you can grab a more pixelated and rough looking poster frame(my apologies if you fix this later). This animation used the simple frame by frame method, but the app also has key frame based animation tools. The app was very easy to use and a lot of fun.
This cute little skull was happy in life and now happy in the afterlife.
