I like Rubik very much, and I just wanted to offer to help maintain the d7 branch of this theme.
I'm a pretty descent maintainer at least I like to think I am ;-)
I've also provided a couple of patches in the rubik issue queue to clean some of the views integrations.
I'm not much of a designer, but then again most of the widgets/elements/design-elements use in the rubik theme have already been developed so there not really much design work to be done.
Anyways, just offering my spare time to help with the project.
Also I'm pretty good with working on the issue queue so You don't have to worry about me committing code that didn't go through the proper issue queue workflow (active to RTBC)
Anyways, no pressure. Just let me know what you think.
