I just wanted to point this post out. This guy is a GC -- why he doesn't advertise it over here I'm not sure. He's from TheGamingTailgate -- good folk.
Had to put him on blast -- he comes on OS and wants to play ninja.
Back on topic: This is great. I had a breakdown of how I thought overlays could be implemented but I don't think I've ever posted it up anywhere. When I find that piece of paper I was scribbling on I'll post it.
