I actually sketched this one extremely poorly since I decided to change the way I wanted dimensions represented halfway through, but the idea is that it works as a circular calendar, with bars that rise and lower in height depending on specific attributes. There can also be a notifying marker at the bottom which singles out a month for specific information. With more data points, I think that this would be a really good idea for viewing information that is month/day of the week-related but not year-related.
