These are awesome. I love the darth vader mini-fridges. Some of these I looked at and thought that the tools could still be used so it seemed like a waste, but they look awesome. LOL. I need to dig up some of the stuff on Pinterest... There are things devoted to cool hidden storage.
You should check out a site called furnituretraditions (can't remember if its .com or .net). They make furniture with hidden storage. It's pretty cool.
