Jonathan Blow is the guy behind the wonderful game Braid and he's now shared a couple of concept pictures from his next game, The Witness. It's not supposed to be released until the end of 2011, but it's supposed to be a 3D puzzle solver that takes place on a mysterious island. Sounds a lot like Myst to me, but that doesn't have to be a bad thing. Check out the concept art here and if you want to follow the development of The Witness, take a look at the game's blog.
