I have an old digital camera...?

My grandparents gave me a digital camera that they don't use anymore, it's from a few years ago, so it's not exactly top of the range, and I was wanting some ideas of what I could use it for. I already have a pretty decent camera, so I don't need a new one, and was wondering if there was anything such as pinhole photography that I could use it for, as I don't want it to go to waste. Thanks!
