Created by Rob Seward, Kunst Bauen is an interactive artwork inspired by 80s video games and the Bauhaus. It lets you conjure pulsating, futuristic patterns with just your fingertips. You can stroke the screen to create smooth, swirling shapes, or tap it to make geometric patterns. Kunst Bauen was originally part of a 2008 art installation in Hamburg, Germany. Now it's available for the iPad and iPhone. The iPad edition features a higher resolution and increased framerate.
