Found a new game - Link-a-Pix. Sucked me in for hours. It is kind of a combination of paint by numbers and Legos. It also gave me an appreciation for what a computer goes through each time it draws an image on the screen, and this image was only 150 pixels square. Each pixel is blown up by a factor of at least ten, so the working image won't even fit on your screen, which makes it possible to easily select individual pixels.
