When we first saw the Ringbow finger peripheral, it was a gangly prototype, tethered to an external battery -- not exactly ideal for a portable tablet accessory. The idea is to strap a D-pad to a user's finger, netting them extra control for touch-based games. Now the duo behind the device is showcasing a self-contained unit on Kickstarter, hoping to garner enough interest to send it off to production. The Bluetooth-compatible band boasts an adjustable one-size-fits-all grip, a nine-way directional nub and a five hour battery life. A $45 contribution buys a standard black Ringbow and a game package, though more generous backers can score additional colors, exclusive hardware and dev kits. Without $100,000 in support, however, the ring won't be minted. Follow the links below if you're compelled to fund the digital circlet.
