The Xenomorph from Alien is totally bad-ass. Now picture one beside your regular, old boring computer mouse. Fire up those brain cells and merge the two together, and you'll probably end up with something like the ultra-awesome mouse that's featured in the gallery above.
The coolest part is that this is a real mouse, and not just some mock-up or concept drawing.
The bad-ass Xenomorph mouse was made by modder Ramses07, who took apart a Cooler Master CM Storm Xornet gaming mouse and assembled it back into this monstrosity. He molded the creepy alien form using clay and voila, instant texture. For the finishing touches, Ramses07 slathered on a layer of glossy varnish to give the mouse 'the effect of mucus.' Sounds gross, but it looks like it totally worked.
