The Millenium Kaleidoscope! by @deathdesu (Des Tini)

The Millenium Kaleidoscope, with the power of perspective! It can create illusions to all five senses, and if used in such a way, can even be used to destroy a human mind. This is done by creating a mass of illusions which form a non-reality; a sea in which the laws of physics seem to change every second, and absolutely nothing is true. This gradually drives the person insane. Weehoo! This is one I made up in my head one day, and now my friend owns it. God save us all.

... Now that I look at it, it looks more like the Millenium Hideously Malformed Baseball Bat. O_o;
