I've been busy playing Riven lately. This is a remake (if you can call it that- I redid it entirely from scratch) of my second image, "Weird Physics" (incorrectly spelled "Wierd Physics" on this site). Ladder and catwalk from Wings. All textures by none other than Me.
Excellent game, excellent graphics. I see the scene you've pictured here. Very good idea, superbly done. The holes are not quite the same, but they are nice the way they are. Without looking to Riven, it is also an interesting idea. Great job!
