It took longer than I expected, but I finally got the Okuda theme for N900/Maemo 5 to a releasable state. The package is currently in the extras-testing repository, so please try it out and vote to promote if you find no major problems. You'll have to reboot after switching themes for various icons and text colors to take effect (Maemo bug 3659). Send feedback and bug reports to lcars [at] synthesize.us (or just post in this thread). The theme includes 403 icons, for which I made a custom template (below). The icon template gets sliced during the build process, just like the rest of the theme. Source is available, so if any other theme makers want to cover lots of icons, this should make that a bit easier. (If you want to theme a different selection of icons, you could make your own template layout with the script at the bottom of this old post by my brother.) Enjoy!
