The very literally named Track Ball Mouse Numerical Keypad Hub manages to Frankenstein an array of accessories into a trackball-style mouse. It also continues the long tradition of lefty-hating trackball mice.
At first glance, I thought this was an actual mouse, and that you were supposed to drag a numerical keypad and a couple USB cables around the desk during use, but it's just a trackball mouse that's meant to stay put. Looks like it's got a standard 17-button keypad and two USB ports, and it connects via USB. If you're one of those Golden-Tee-loving types who's into trackballs, it's available for a kinda expensive 5,290Yen ($60). [RedFerret via OhGizmo]
