Yeah, I've seen it -- it's Tinguinha, same guy who did the instructional.
Spider is too tricky to pick up from a mag though. For example, I never knew that you need to keep both legs at opposite extensions at all times -- one extended fully, the other retracted fully, alternating between the two, spinning back and forth. I also never knew how to pull spider properly, or how to launch sub attacks from spider. The instructional dvd is good at explaining that kind of basic stuff.
