What to do with old laptop?

I've recently had the urge to use an old laptop for something, but have no idea what I can use it for. It's 8 years old, not sure of the specs, and currently missing the battery. I can probably find the battery if need be and still have the power cord anyway. Would this be at all useful for anything aside from being a paper weight?

Install an OS on it that you've always been curious about.

I suggest the 50 megabyte Linux Distro.
It's called Damn Small Linux
