There's already at least one Portal cartoon in production. That one, however, looks like something Dreamworks would come up with. If you'd rather a Portal cartoon look more like something Ren & Stimpy creator John Kricfalusi would dream up, though, you might want to take a look at these.

These pieces are the work of artist Sandra Rivas, whose style is heavily influenced by John K.. What's cool is that she's turned all the cores and computers into people, and in doing so, has absolutely nailed them. Especially Wheatley.

Portal 2 on the PS3 is getting Move support and some "new" levels. It's also playable at Sony's E3 booth, so we popped on over to take a look, see how the Move actually worked with the game.

Developers Sixense have announced that a bunch of new Portal content is coming to the PlayStation 3. It's called Portal 2 In Motion, and is DLC for the existing game that takes full advantage of Sony's PlayStation Move peripheral.

Crafted as DLC for the core game, P2IM was developed by Sixense, and brings 20 new levels to the game, along with new challenges and gear. Sixense will also be bringing Move support to the core Portal 2 game on PS3.

UPDATE - Looks like much, if not all of this content is the same PC users got hold of as part of Razer's exclusive Hydra DLC.

Portal 2 Spoilers ahead.

This version of "Cara Mia" isn't as lovely as when it was sung by the turrets in Portal 2, but it might be even cooler.

A single button push takes a Portal 2 cube on an incredible journey through Ben Perry's astounding Rube Goldberg-inspired custom level.

Portal 2's brain-twisting puzzles prepared players perfectly for creating their own convoluted level creations. The recently-released level editor has been getting a strenuous workout by some incredibly brilliant minds.

Ben Perry took a couple of hours to put this all together, limited only by his imagination and the number of objects the editor allows players to work with.

And to think this is only the early days of the tool. It's almost scary to imagine what's still to come. I'm all tingly.

Portal 2's latest DLC doesn't just include the chance to create your own maps, it includes the chance to run around them hearing the delightful JK Simmons - aka Cave Johnson - command, dictate and berate you senselessly with almost half an hour's worth of new content recorded just for the level creator.

If you think sitting and just listening to this for 25 minutes is boring, boy, you're about to miss out.

WARNING: There's technically some spoilers in here.

Man. I do like a good Portal 2 remix. This one, however, is on another level.

It was created by Will Bedford, and I've been listening to it all day. For real. Maybe it's the happy pop chord progression. Or the kicky beat. Or the triumphant Cave Johnson breakdowns. Or the double-time section.

Or I don't know, the whole thing. Give it a whirl, you'll see what I'm talking about.

Here's another quick one, called "You Monster." Excellent. Sing it, Cave!

(Thanks, Steven!)

We've seen some ridiculous creations in games where level editors are involved. Portal's version of this that was released yesterday is already beginning to show some interesting level designs of its own.

This Portal 2 player managed to construct a binary adder using the familiar in-game items. The DLC's item limit forced him to end the project with a binary readout, though he was hoping to take it further with a numerical display.

This might not be as monstrously complex and powerful as some more ambitious Minecraft projects, but I imagine this is just the beginning.

You know those really cheesy songs that you're not supposed to like, but they're too catchy not to? Jason's familiar with the concept. For him, it involves his obsession with "Call Me Maybe." And he's not even embarrassed by it.

Although the context is something I can totally stand by—namely, anything and everything Portal—I'm not too terribly keen on the musical stylings. But it's just...too...damn...catchy.

Today's the day when the amount of teleporting happening on computers anywhere will start increasing exponentially. Or in the words of Cave Johnson, "You should be designing test chambers, right now and at all times, or by God I will fire you." The Perpetual Testing Initiative DLC that lets players create and share their own puzzle rooms for Portal 2 hits Steam today. Go make something tricky or beautiful or both.
