Treo Easter egg taxi
Go to Preferences->Power and in the bottom right draw a small clockwise circle. An Easter Egg will appear. Then a yellow taxi will randomly cross your screen.
It may take you a few tries to coax the Easter Egg to appear. Try re-drawing the circle slower if you don’t succeed at first.
The Treo 680 also has a worm Easter Egg. Go to Home->Prefs->Power and press the option button, then the # button. Let go and wait a few seconds. Changing to another application makes the worm go away.
