The first and original Scrambled V was developed by the Biowup group in Hilden. Aidan Burns found a clever way to not only describe the already existing pattern, but to work out 27 possible variations. By now, all of them have been juggled and while some are harder than others, all of them are (obviously) jugglable. Aidan´s notation is from the viewpoint of the manipulator, which may lead to confusion in reading them as most jugglers tend to see scrambleds from the viewpoint of the feeder (who, incidentally calls out the beats). So, Ed Clark rearraged the notation to the viewpoint of the feeder. In the document linked here, you will find tables with both Aidan´s as well as Ed´s notation and a page of general hints.
