Conformal Decals adds a set of decal stickers to the game Kerbal Space Program (KSP), as well as providing a framework for creating your own decals which conform to the surface of the parts they are attached to.
This means that you can do other stuff with them, like make your own stickers and icons and suchlike. Especially interesting because it has the Semiotic Icons that were used in Alien.

A service that will print high-quality stickers, business cards, and what have you out of images that you send to them. Their prices are quite reasonable, also.
A store chock-full of C'thuliana, from stickers to shirts to books. Fun to poke around in.
Someone made up stickers that you can download, print, and put on all of your laptops over the hard drives in case you ever feel the need to run a power drill through them.
