I just finished the beta version of my Punkd theme. It still needs some documentation and finetuning but it's good enough to use already.
You can download the files here: http://peterboorsma.nl/category/themes
Enjoy!
I made a list of WP themes that I want to port to PivotX:

http://themes.thaslayer.com/2/
I'll let you know when they are finished.
