You were talking about themes, so I thought I'll publish a version of mine, i recently made for a little project. Just to say, its aim was more to give a flexible backend, to configure the frontend view layoutwise. So it does not offer a nice style or a brilliant design.
Take a look. If you'd like to contribute, write me a message.
P.S It's not available on Pagekit's marketplace. Just download, zip it, then upload it to your page. Should work out of the box.
Thanks and cheers
