Software artist Rumi Humphrey is pleased to announce his new app Slewpi 1.0 for iOS. Slewpi is an amazing new way to explore painting, music, and animation. It’s super easy to use, just paint on the screen with one or more fingers and choose different colors and brushes to change the way the strokes look and sound. Slewpi records what you do and plays it back in a loop. Never before has creating music and animation together been so easy.
