I'm new to themeframe, and fairly new to WP, but I'll try to give you a couple of answers.
First, you can watch the video
. It shows the Themeframe workspace in action
The attached .zip is the the default starting point in Themeframe. You can use it in WP, just load it the same as any theme.
In it's current form, this is the only a starting point. You can save copies of your own work, and modify them in different ways going forward. And, save them at any point.
There are no "theme templates" included in Themeframe other that it's default.
I suppose that users could share their work with each other if they wish.
Hope that helps a little.
