Over at Computex in Taipei, Global Link is showing off a "Ring Mouse" which straps to your finger and allows for cursoring on pretty much any surface, including your thumb. The plastic case and strap means that this is probably not something you'd want to propose with
, but the design is chunky enough so that unsuspecting passers-by in cafes will understand why you're repeatedly stroking your thigh. It's hard to tell how the mouse operates (is that a ball or a frickin' laser?), and we've no idea about pricing or availability, but that tends to be how it goes with these zany foreign gadgets.
