Just ran into this neat little nugget. Machinarium is a puzzle game with great artwork. I think of it as Myst lite. Because of rampant piracy, they’re holding an “amnesty” sale where you can purchase the download version of the game for only $5.00 (discounted from $20). The sale ends on August 12th. The website has a demo of the first three levels, so you can see what it’s like. They also have some wallpaper images available for download. Runs on PCs with Windows or 32-bit Linux, and Macintosh computers.
