Found this on TGN today:
Looks really neat, plastic sprues of interlocking tiles with low walls surrounding them. This is an instant buy for me, it's just plain perfect.

Really like the peg-and-hole system they've got for fitting the pieces together. Setting up a board will be like building a lego set.
