Cakewrecks ("When professional cakes go horribly, hilariously wrong") did a weekend special on science fiction cakes. I don't think these qualify as cakes gone wrong. These are what a cake should be!

Update: Thanks to the alert commenters below for in-cluing me to the fact that Cakewrecks weekend features are devoted to awesome, rather than awful, cakes
