Coign of Vantage is a picture-matching game. An image appears in the top-right corner, and you have to match it by rotating a 3d cluster of squares. The cluster initially looks like a random jumble, but from a certain vantage point they form the example image. Confused? You won’t be when you give it a go. You just keep going until the time runs out… which can take a while since you get extra time for getting a puzzle right.
Exercise that spatial awareness… or, alternatively, just enjoy the game :)
Needs flash and has sound – though you can play with the sound off
