Mulit-User Composite View (IMSCAN),
originally uploaded by John Resig.

I wrote a new visualization for IM user data today. The following image shows a two-week composite view of a user and its buddies. To acheive this, I essentially took a 24 hour view from a user, added an opacity, and layered each day on top of each other. The result is this interesting composite view that's really informative. (The darker the area, the more active the user is during that time period) I later added in the ability to drag-and-drop users, to make it easier to compare one user to another. We will probably be launching this service very soon - I'll be sure to let everyone know when that is.
