If you haven't checked out this WiiWare title, you are really missing out. I'm not sure if it is available in the UK or ANZ, but I played it yesterday on my mates Wii. You basically build structures out of different coloured goo balls while attempting to navigate across different terrains.
I think IGN has a review of it online. Somebody told me it is also available for the PC and Mac, but I haven't confirmed it. I'll see if I can post a screenshot here soon.
