Great for CAD apps, Google Earth, and that old game Descent, this M-3D1UR mouse lets you move and rotate on the x, y and z-axes with just one hand.
The mouse has the regular scrollwheel along with three separate joystick-like knobs positioned left, top, and right of the wheel so that you can move around in the three axes. For greater precision in both fragging and house design, it offers 400, 800, 1600 and 2000 dpi resolution.
At a price of 12,800 yen ($108), it's pretty affordable too. Who cares if teenage boys buy this to rub the knobs like nipples?
