These are the tumblr themes I designed early in Tumblr's life. They are most likely very out of date with Tumblr's current feature set. They're all available for free, with loose licensing. All themes are installable more directly by visiting http://tumblr.com/themes/by/cubicle17.
These themes are provided as-is and without support. It's likely I'll answer simple questions, but I will not offer or respond to requests for customizations to these themes.
Feel free to use and modify, but please give credit to me somewhere (doesn't have to be visible; can be in a comment in the code).
