css stylechanges -- how do they do that?

[munna]

Hi,
I would like to give visitors to my page the option of choosing from a number of different stylesheets. I remember seeing a javascript to do this ages ago, but can't find it now. Please can anyone tell me how to do this, or send me a link for a suitable code snippet?
Thanks,
Munna
