Batman Minifigure Cake

Look at this! This is art! This 3-foot tall cake was made by Mike McCary, possibly for a wedding, who knows, but who cares!? Look at that detail! This is one of the best cakes I've ever seen, and that includes the stuff I've seen the Cake Boss make.

Arctic Plane

 The fourth in blakeydrums' series of micro builds. This one is rather nice.

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.

Lego scale model of NYC

 Not really. But it is really cool piece. This digital render was made by 3D artist JR Schmidt, using maps and satellite data. This should be made. I think it would make for a really awesome build.
