Creative Decor: Painted Ceilings

I thought painted ceilings should make it into the creative decor section of my blog as they are often neglected. The trick is, that it definitely needs to be done right, if done wrong, the room can seem smaller and shorter, so it's very important that you know what you're doing. Here are some examples to help inspire you to do something with that fifth wall.
These pictures can attest that a painted ceiling can be done in any room:
