Lucky Charms, Xmas Ornament, or Computer Mouse?

These star and strawberry mice look more like something you'd hang from a Christmas tree or even put in your mouth rather than connect to your computer! I guess there's nothing stopping USB wackiness, but could you imagine using one of these mice as your everyday mouse? Yay for fun factor and cuteness, nay for practicality and being ergonomically-friendly. These European beauties cost $44 each.
