Announced at http://newschoollearning.com/theme/contest/, I decided that this was the perfect excuse to actually finish the theme that I’ve been developing for over a year.
That year has been interesting, since almost every single piece of code related to themes has changes multiple times, requiring a number of theme rewrites to keep it all up-to-date. I seem to repeatedly have this issue with writing lots of code for something that’s in active development, and then rewriting that code to keep up with the API changes. >.>
The theme uses one of the new custom renderer classes to output HTML5, and includes a number of admin-configurable settings such as colours, welcome text, and the site logo.
My entry is called Silvern.
Edit: I almost forgot to mention: All the code for this theme is available on my github account. Enjoy :)

Congrats on finishing it :)
STOLEN!
=D
Before you “steal” it, note that there might be bugfixes and some tidying up over the next week as I receive feedback. :P

Realise these posts were put up ages ago, is Silvern still available – it looks really cool and would be good to take a look at, but github link seems to have died!
