This is just a quick n dirty one. Compressed with a stub launcher and the C runtimes moved around. But it's a cool chess program. In 3d. And it's portable. Just hit ESC to bring up the menu to adjust settings, difficulty or exit. It doesn't maintain settings (The app itself doesn't do this yet). And it'll be slow on older PC hardware since it is 3d. But any PC made in the last few years should have no issues with it.
UPDATE: Almost forgot, right-click your mouse and move around to rotate and spin the board. It's kinda cool.
