Portal 2's Wheatley fits extremely well as the voice of 343 Guilty Spark in Halo: Combat Evolved. This mashup takes the cake.

These Portal 2 personality cores aren't going to space, they're just going to your stomach.

Valve has done a great job lately at making their games look cartoony, but never quite like this.

Presenting You Monster, a fan-animated 2D short that imagines Wheatley and GLaDOS in humanoid form. It's the best thing you'll see all day.

A Redditor has done fantastic work for science by compiling a gallery of Portal 2's wall decorations. There are more than 30 in the collection, so chances are you missed a couple as you cruised through Aperture's numerous facilities. And of course, they're all hilarious.

Thanks to Source Filmmaker, we get gorgeous fan videos like After Aperture.

The short film imagines what would happen after the end of Portal 2, set to The National's Exile Vilify (also from the game).

Sick of perpetual testing, these angry androids took to the streets and learned how to shout obscenities.

Sigh. Robots these days.
