"A mobile gaming peripheral by the name of \"Ringbow\" hit Kickstarter recently.  The bluetooth-enabled device features a D-pad on its surface, potentially solving the \"pesky touchscreen D-pad\" crisis plaguing some mobile games, such as platforming titles.A $45 pledge will put one of these Android and (soon to be) iOS-compatible rings on your finger, along with a small collection of games developed around the peripheral.  Pledging $55 grants developers early access to the device's API.  Ringbow will go into production if the project meets its $100k goal by July 22."^^<http://www.w3.org/2001/XMLSchema#string>
