BBC.co.uk have a great little site, called Pinball, that is designed to help pupils throw their ideas around in some simple, yet fun, ways.

A few good little ideas on here. One of them, is a great way of making a one armed bandit which selects from your choice of text and uploaded images. Quick and effective.

There is also a simple mind mapper, image editor, and sorter. Good to link from one to another.
