The Iron Giant

 The Iron Giant by Calvin Sun (superesc).

Mini Greek Temple

 A miniature Greek temple by blakeydrums, small enough to fit an iPod Nano container. This isn't the most impressive or creative build, but I think it's pretty neat. He mentioned on Reddit that he may start a whole series of builds like this, so that may be worth watching for.

The Building Blocks of Life

 Reddit user devlinux posted this really neat build to the /r/lego subreddit. The strand doesn't actually code for anything, but it still makes for a rather fun and interesting build.
