Facemaker is an educational game that lets you create the silliest looking faces anyone's ever seen.
You can choose from a wide assortment of eyes, ears, noses, and mouths, then make your newly created faces blink, wiggle their ears, wink, or razz you. You can even play a "Simon Says" type game where your face will do some kind of action and you have to follow along!
Facemaker was released for the TI-99 in 1970 and is a great example of an early interactive game that teaches children about creativity and self-expression.
