Last year, my novel Makers was published and syndicated free as a series of 81 blog-posts on Tor.com. Tor had the insanely creative people at Idiots' Books produce 81 interlocking, tesselating illustrations, one for each installment, and made a sweet little Flash toy that let you play with making your own meta-illo by moving the tiles around.
Now, Idiots Books have released a limited edition set of physical cards that let you play the tile-game on your living room floor. I handed these out to folks on the For the Win tour, to great reactions. They're $12, and you can get them now.
