How about a contenst on a "2D Maze Generator"??

Sounds interesting. How exactly do you think the contest should be? Generate a maze from what?
Alternativly we could do some maze pathfinding - but we already had that to some degree.

The current system wouldn't support generating mazes since there needs to be only one possible solution.
I've suggested maze solving already, but it would have to solve for the shortest possible route (for the same reason).

Ok... my original idea is not compatible with the system...
Instead something like 'from a connection list build the related maze'?
Maybe too simple?

Maze solving sounds good to me. The input could be generated so that there it is guaranteed that there is only one possible solution.

Ciaran, you're not quite right there - Code Golf now supports challenges where the output can be checked for validity ...
