Windell Oskay made this 8-pound cake with a 3D printer called a CandyFab 4000:

The shape is a 3/4 twist mobius strip with a square cross section and windows cut at regular intervals in all of the sides the side. Even though it's hollow, it still weighs seven pounds and fourteen ounces-- that's a lot of sugar. We're bringing this monster to Maker Faire this weekend, so you can see it for yourself, too.
