I'd suggest a digital camera Ashleigh.
If you have one already, go wild with photography. Learning how to use the camera is quite challenging and even if its one of those point-and-click cameras (no knowledge of photography needed..just point..and click!) you can still have loads of fun with it.
Take pics of your house, your surroundings, your hand, your toes, make collages, take pics of the moon, take take take pics.
The better you get at it the better you feel. Its hard to describe how awesome it is to see that THE image you wanted to capture is in your computer screen and that YOU took it and its yours..all yours
