This is too cool. Hoopism.com broke down every NBA slam dunk contest (1984 to 2010) by dunk, year, and score. You can see video footage of the actual dunk by clicking on the circles in the graph.
The coolest part of the interface is being able to quickly get to any dunk without having to search through hours of video.
You don’t leave the page to see the videos. Click the pic and check it out.
