This is a very generous topic as there are lots of weird computer mice in the world. In their pursuit of making unique and attracting computer mice that would be out of the ordinary and this way attract people to buy them, computer mice producers have tried different designs, some of which really weird and unusual. Look for example at this scary ghost computer mouse!

It looks like the ghost in Scary Movie, except the colours are the other way round: the eyes and mouth are black while the rest is white. It is a corded mouse and the eyes of the ghost are actually the two left and right click buttons and the little scroll wheel is situated between the eyes. I can't say the design is very ergonomic, especially with the pointed end of the mouse that could be really annoying.

I think this gadget is the perfect gift for Halloween when ghosts and witches are very popular. Or it may be the perfect gift for your rebel friend who likes Gothic style and wears only dark clothes with bones printed on them and chains and all the stuff.  Or you may keep this weird computer mouse as a scary accessory, because I can't imagine using it for more than five minutes.

The first picture shows another weird computer mouse. This time some Russian kids turned out to have more imagination than it is necessary or even sane. They took a fake hand grenade, cut it in two and transformed it into a really weird computer mouse. They added all the necessary wires and even used the trigger as the left click mouse button.  It is perfectly functional and looks very much like a real hand grenade, but it's only a gadget, as you can see from the pictures above.

The colour is perfect, the shape, too. Just the underneath of this object shows you its real purpose and what it is used for. But if it rests comfortably on your desk and you don't know what it is, you can surely mistake it for a real grenade and get frightened to death.

That is why I think this is a good gift for your enemies or for people with a really good sense of humor. After all, you don't want your best friend to start screaming and call the bomb squad when he finds your gift under the Christmas tree.  Of course, these are only two of the many examples of weird computer mice existing on the market, but unfortunately I do not have enough time and space to show you more than that, but I think you already have an idea about this kind of computer mice.
