n00b: additional themes

[Keith Hurwitz]

Folks - curious to know if there is a community centered on themes - I dont have time/interest in creating my own, but would like to know if there are sites that have created themes that I can...."borrow" in their entirety. Any help appreciated...

I'd be interested in something like this too.
Does anyone know how to turn off certain default themes ?
