Free theme change ...These are themes for blogger

[enliven]

converting a wordpress or blogger theme is a pain in the rear end, mostly because they're formatted in a completely different way, and inside the theme files are copious references to wp or blogger specific functions. if you find a theme you really love, you could install wordpress or blogger, install the theme in it, then visit the wp or blogger site and save the static page that's created from all the php functions, then open it in an editor and replace the content parts with the getsimple function calls.

in other words, it's so much work that most people wouldn't bother.
it's easier to create your own really nice getsimple theme from scratch.
