Anything that has a Forcefield Mode has to be a little cool no? Robert Tubb’s Masters degree project The Wablet has such a mode. Another good iPad app for glitch and drones.
“Scanned Synthesis is a way of generating complex tones by scanning an interactive model of a physical vibrating system. Scanned synthesis provides a good solution to some of the main issues in digital musical instrument design, and is particularly well suited to multi-touch screens.In this implementation, animated, vibrating mass-spring networks with a wide variety of configurations can be displayed. These can be manipulated by touching, dragging and altering the orientation of the tablet. Arbitrary scanning paths can be drawn onto the structure using the fingers.” – Robert Tubb
