Don't forget that you can also customise the Gespaa theme.
The effects of about 5 minutes work can be seen on this very site. The picture is the same one that I had as a header before the redesign.
For future reference (in case the design changes again), I've also uploaded screenshots so that you can compare the default look of the theme with how it looks after some minor customisation. If you have an interesting customisation of the theme, feel free to post a comment with a link to your site.
