There was small GBC circuit at the LUGPol’s event last week. It was built by Jahoo, Maras and Solic.  It looked like that:

I also have 3d version of it under this link. It requires some 3d hardware to watch, be it 3d googles, 3dTV or just plain anaglyph glasses. You can choose your option in the player.

And if you happen to have Nintendo 3DS, here is a file you can put on your device and see it on your 3DS. Right click on the link, select save, then copy it to your media folder on your Nintendo SD card. After you put the card back in your Niny, you can find GBC video in your camera app under view photos.
