Here is a PDF with my sketches for Cheese or Font.
One game that I think is beautiful is Dots the iPhone game. I think the extremely simple design, use of white space, and color management make this game great. The design is so plain which makes it not distracting and hyper focused. The whitespace is great because you clearly know which dots are a part of the game and where your score is. Plus, the colors are pleasing and create easy associations for the player.
