Once upon a time the inPulse was a BlackBerry peripheral, but no more -- now, it's a fully programmable device-agnostic Bluetooth wrist computer. That's because its manufacturer Allerta released an SDK this week, which lets the 52Mhz ARM7 processor and 8Kb of RAM within display whatever you'd like on the 1.3-inch, 96 x 128 pixel screen. Like the time of day or this tiny, practically unplayable 3D game. Yours for $149.
