From Robert Jen:
LetterDraw is an educational program that teaches children how to write letters and numbers. It teaches both the upper and lower case letters as well as numbers from 1 to 10. LetterDraw animates the drawing of the letter to show exactly how it is drawn and provides an optional template (dotted lines) for the child to trace over. On color devices, the colors of the model, drawing, and dots can be customized.
