looking for similar theme to this

I’m looking for a FREE theme very similar to this one: http://ithemes.com/demos/charlie/#

I like that it is clean and simple, and that is has a couple of call to action buttons.

Does anybody know of any free themes very similar to this?

Or, one like this, with rounded borders, would be even better. http://www.vflyer.com/main/marketing/home

Thanks in advance.
