Looks great, zork. I love your ideas. Your 'scroll frame revelation' made me laugh
It actually inspired me to try and use a scroll frame myself for some to-do list I'm working on. Sliding panel with transparent frames (so no lazy moving behind the parent frame) \o/
The possibilities... they are endless.
Edit: You could also make a pretty cool experience bar with it. A full circle represents one level. You have a segment for the current experience, then a second segment starting at the end of the first one representing rested experience. If you make the second one semi-transparent, you could see how far it overlaps into the next level as well, something which traditional experience bars can't do.
