I like it and haven't yet had time to build a standard compliant theme with similar colours but a slightly different look.  I also want to make it work better in 800*600px browser windows as well as having a similar variable width theme.

 If you have a favourite Joomla or Mambo theme then send me it (or let me know where it is) and I might include it in the theme selection box which is usually found on the front page
