From the Tux Paint site:
Tux Paint is a free drawing program designed for young children (kids ages 3 and up). It has a simple, easy-to-use interface, fun sound effects, and an encouraging cartoon mascot who helps guide children as they use the program.I'm amazed how intuitive and how well designed this is for the child.
