What you see in the YouTube video above will definitely tickle you, as it is one mouse that works otherwise. Why do we say so? Well, it will apparently move away in an attempt to escape the clutches of your hand as you try to grab it. This is made possible thanks to a light sensor which will detect your hand’s shadow, where a motor will then turn on for a second or two to make its escape. Perfect for a party trick, and it would be even better if you ask someone drunk to use the computer. This is a DIY mod, so you can’t just waltz into any computer store and pick one up.
