Live Dangerously With The Hand Grenade Mouse
Some people like to have the "tough guy" image in every aspect in their life. Usually when things are made to appear tough, they don't. But in this case the hand grenade does, at first, promote hostility when a person first sees it.
The person who developed this actually made the mouse out of an old hand grenade casing. There isn't much out about this or whether it will be up for sale as a product, but it was modded and posted at what I think is a russian website here. The function may not be perfect or work well for gaming so it's just meant to look cool. He also activated the trigger as the left mouse button. I would also imagine that it would lack comfortablility so if you work on a computer for long hours, this might not be your best mouse of choice. None the less, it still looks cool.
