Theme Maker has finally proper home page. It's a bit small for the time being, I'll try to add some downloadable themes there tomorrow. For now, it's just to have a tutorial on theme creation and download links.
If you have created themes with theme maker and would like me to link to them, please mail me at email@example.com. I can also host the .deb files if needed.
Also, please take a screenshot of your theme so that the download page would look better.
