When you want to play with Linux in almost every case, you will turn to a major distribution. A Linux-distribution (distro) is the basic GNU/Linux Operating System (the Kernel - for the latest kernel go to http://www.kernel.org) together with a list of programs that enhance it in many ways. You can even create your own distribution. As far as I know, there's no restriction whatsoever.

There are quite a lot of different GNU/Linux-distributions out there, each with their specific pro's and contra's. You should check them out for yourself to see which one suits you best.

There's an (almost) complete list of all GNU/Linux distributions at http://www.distrowatch.com.
