This is pretty innovative. This photographer used Devkitpro to create his own interface from his Canon DSLR. He was sick of bringing his laptop around everywhere he wanted to shoot, so he utilized the DS's compact and "instant on" nature. Features include: HDR intervalometer-based shot bracketing, remote shots in bulb mode, as well as a sound-based “Clapper” control. I do not know what these mean, but the individual tools for doing this kind of stuff run for over $100 USD each. This is very cool indeed!
