Of the millions of apps out there, none quite capitalize on the sheer fun and beauty of interactivity the way that Scott Snibbe's do. Combining "painting, animation, art, science, and gaming," the San Francisco, CA-based digital artist originally developed the gorgeously elegant interfaces (all part of his "Dynamic Systems Series") in the late '90s and showed them in galleries until the iPad and iPhone came about.
Recently top-rated in iTunes, Gravilux starts with a field of tiny evenly-spaced stars that dance and swirl around fingertips in a simulation of gravity. With the ability to "tease and twist the particles into galaxies, or explode them like a supernova," using it feels a little like playing God.
Bubble Harp draws cells on the screen to create fragmented images in the same way that bubbles or cells develop in nature. Settings allow for recording movements or for streaming of bubbles from your fingertips.
Bringing Snibbe's concepts to a slightly more earthy level, Antograph uses ant behavior as the framework for this app. Touching the screen conjures a stream of ants and leaves an invisible chemical trail, which tells ants where to go and creates a pattern—from which the ants also lose their way.
