Help with 7 segment LED

[snake126]

Hello everyone, I am working on a project where I would like to install one of these:
http://cgi.ebay.com/10pcs-0-8inch-7...317?pt=LH_DefaultDomain_0&hash=item483fd1c0dd

and have it display completely random things (dont even have to be numbers) How could I possible go about doing this?

Thanks

The more I think about it, it doesnt even have to change randomly. Is there a way to just be able to flip a switch, the display powers up and have it wired to show something that isnt a letter or number? something that could be percieved as "alien" is what I am getting at.

If you could show me how to do this or point me in the right direction it would be awesome
