I was just thinking the other day about the no fingers control issue.
I saw
here that a company is making a glove controller that works with a few systems, including PS2. Anyway, if they make a lefty version, that might be of interest to you. Check out the link for more, but here\'s a quick synapsis.

P5 provides gamers with an ergonomically designed glove-like device, which controls the fast action in 3D game software through diverse hand gestures. Pull your trigger finger in 3D space and the on-screen gun shoots in real time. Flick your fingers away and a game character is thrown against the wall. Lift your palm and an animated helicopter slowly rises into the air.
P5 uses the latest in Essential Reality\'s proprietary bend sensor and tracking technologies to enable full interaction with a 3D environment. Fully USB compliant, P5 will be compatible with Macs, PCs and next-generation gaming systems, including PS2 and Xbox.
