The amount of modeling attention lavished on these computer mice is a testament to the gaming market's fertility. This Mercury M2 gaming mouse, by Chinese manufacturer GravaStar, has been skeletonized to get the weight down to just 79 grams. (If you're a non-gamer, the mouse sitting on your desk is probably closer to 120 grams.)

For gamers who prefer a heavier mouse 9for precision over speed0, their Mercury M1 variant is made of magnesium alloy (as opposed to the M2's plastic).

The symmetrical design is to accommodate both left- and right-handed users.

It's available in a variety of finishes, including an amusing "Battle-Worn" finish that has been artificially distressed.

The dongle that plugs into your computer has received the same skeletonized aesthetic treatment.

The M2 runs $80, while the heavier M1 rings in at $100.
