Yeah, thanks for catching my vagueness. I've been playing with these concepts in various forms starting in late 2006/2007, but realized I never got any good footage up.
In my haste, I wasn't clear enough and glommed some ideas together. With repeated linear extension one makes elliptical obits, but never a loop/momentary isolation. This is what is happening during the continuous linear extension weave.
What I'm calling a pulse accelerates out to an ellipse, but as it comes back in, your hand slows and the poi head over takes the hand into a loop or a moment of isolation. Rovo had some videos of basics from buzzsaw up on DMP in 2006, but was just calling them ellipses. Because of the moment of isolation, it is possible to turn your hands around a unit circle or closer-to-point iso center and pulse out in a different direction. I'm doing a sloppy job of it, but that is what is supposed to be happening with the fountain.
I'd now like to differentiate "pulse flowers" from other elliptical flowers Zan talks about.. The procession of the hands pulsing moves in a sequence that is equivalent to inspin, but you get pulses that look like long petals, and a small iso center... it looks a bit like a daisy.
