Motionphone HD is an animated drawing application by artist Scott Snibbe that allows users to create works that respond directly with the touch of their hand. Customize color, shape, transparency, speed, zoom, frame rate, and translation across an infinite plane. Create these hypnotizing drawings alone, or search for other iPads, iPhones, or iPod touches for a collaborative animation session! Play music while you work, and endlessly undo if you aren’t pleased with your results. With up to 30,000 animated brushstroke possibilities, Motionphone is an excellent creative release with clean, colorful results. Record your creation and upload to Facebook, Twitter, or email. Motionphone HD is available for $2.99 in the iTunes Store.
