Hungry Crocodile: An experiment with webcam/marker-based interfaces

For the July Berlin Mini Jam, I experimented with the input interface. Turns out a cardboard contraption with fiducial markers and Unity3D + NyARToolkit on the software side makes for a fun crocodile maw control system! I didn’t finish the game (you can’t win or lose, you can’t even score), so I declared it a story-focused artgame. That’s how it works, right?

Hungry Crocodile

The crocodile is hungry and wants to eat,
but despite all the food, it can’t!

Because of explosions.

Moral of the story:
Explosions make everything better.

You’ll need these two markers: Hiro and WD (taken from here).
You’ll also need cardboard to build the maw.

(If you’re wondering why I didn’t use the standard Hiro & Kanji markers –
I just took what was lying around from earlier experiments.)

Despite being unfinished, it was a lot of fun to present:
