So just as a follow up. It was a great day in Cambridge but the fever pitch inter-university juggling rivalry as well as the high ball juggling standard (people without a consistent 5 ball cascade being deemed "beginners" for the day) meant that, sadly, there was very little kendama time.
Anyway, I got a fancy new GoPro camera last week and made a video of the day. As it's my first with this camera any feedback/suggestions on the video would be greatly appreciated as I'll hopefully be doing something kendama related with it in the near future. Enjoy!
WARNING this video contains NO KENDAMA!!!
