Also not OP, but I'll second archagon's list. If you're specifically looking for something that fits this thread's constraint of visually stunning, one-man indie dev Escher-style puzzle game, I feel an obligation to point you at Antichamber [0]. It's got some of Echochrome's starkness to it, but with some very nice writing/dialog(?) bits that play off the game's puzzles well. Most people will find something delightful about it, though be ready for a slower paced, introspective game. It knows you know it's a puzzle game, and will punish you for it :) (I should note that Antichamber seems to have been in development before Echochrome or Fez, and as such likely deserves the originality that has been showered on it.)
