Slackline? Slackline!

Is slacklining a sport? Is it a workout? Check it out. Computer scientists are performing Shlaer-Mellor object oriented analysis and constructing an xtUML model of the sport. One goal will be automated scoring of the technical aspects of the movements such as height, air-time, number of flips, time on the line, etc.
Look for the model to be posted soon.
This is a totally fun modeling project!
