For something completely different, consider making a device that can draw patterns on an egg. Although the concept isn't new, Arduino forum member "Msquare" has demonstrated their own version using a stepper motor, a servo or two and some basic hardware. Once the motor control and servos have been aligned properly some interesting effects can be created on the surface of the egg with a felt-tip pen controlled by the device, for example:
And doing your own is much cheaper than a commercial kit. So for more information and the sketch, log in to the Arduino forum. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
