It's been available on the Japanese DSiWare market for a few weeks now, but a recent ESRB rating has revealed the 16 Shot! Shooting Watch is on its way to North America in the near future.
Although it sounds like a rather James Bond-esque gadget, the Shooting Watch is a device to help you find out exactly how quickly you can tap a button in a specified length of time. Hudson's Mr Higgins – otherwise known as Meijin Takahashi – rose to fame for being able to make 16 taps in one second, so who knows? Maybe the same could happen to you if you can blitz his record.
Hopefully this one will stay at the 200 Points mark from its Japanese release so if you feel the need to bash your DSi screen repeatedly at least you can do so cheaply.
