They snuck it up on me! They've restarted the biweekly Geomorph Contest over at Inkwell Ideas. They lost some momentum, I believe, when they put it on hold for GenCon (and I totally understand why -- they've got a lot on their plate for the Con, and I appreciated them putting it on hiatus over just not saying anything about it and leaving us in the dark). Therefore, they've extended the deadline for the current contest, which has the "building" theme.
I had been watching, but when they didn't restart it right after GenCon, I kind of lost track. I'm happy to throw my hat in the ring again, although my stuff pales in comparison to the artists that submit stuff.
