RdL hollow triangles and 100mm Mr. Babache stage balls. Both unmodded, they just work really well together.
I discovered that you could trap the balls in the triangle during winter 2010-2011. I did film some super basic stuff back then too, but never edited it into a real video. This is still pretty basic, but it covers much more and I guess most people can watch this and see some branches of tricks/concepts emerging that could be further researched.
Main influences for this was Jay Gilligan, Jackson Ford and myself from 2008.
I guess this is exactly what I said I would do, go back and find stuff I never finished and finish it. I have transferred the contents of the tapes to my external HD now.
