Squigglish!

A simple drawing app for the casual doodler with just one purpose: to add lines that wiggle. At first, it might seem like the app simply animates static images by adding motion to straight lines. In reality, it’s employing an animation effect called squigglevision that involves drawing the same image several times and looping the drawings together to create movement. Developed by mathematician, Olivia Walch, the app makes this effect achievable for anyone. Upload or take a photo to draw on, or start from a blank canvas and create your own masterpiece. When you’re done, you can export it as a GIF or movie. Free for iOS.
