Make and decorate a cake in the shape of a three-dimensional cat for a birthday party or other special event for a child or a feline fanatic. Use colors for the fur that resembles a special cat in the guest of honor's life and use fondant decorations to add realistic-looking eyes and other features. With a little bit of practice, even novice cake decorators can easily turn the cake into an edible decoration, worthy of becoming the centerpiece of the party.
So you're a geek, or you want to get in with that techie crowd. You can get together with other geeks and have a heck of a Halloween, no matter how "white and nerdy" you are. Just do what comes naturally-to a geek.
