For example, from Parallel Waves, Fractal Tally-Ho would be: 1/2 Circulate; Center Wave Cast Off 3/4 & 1/2 Box Circulate as Outsides Trade; Those who meet Arm Turn 1/4 as Others move up.
The problem with the concept is that dancers have a problem determining what is a 1/4 turn, and what isn't. For example, from a Tidal wave, on a Counter Rotate 1/4, do the very centers do a 1/4 Arm turn or not?
The original definition of Fractal said that any call in which dancers hold on to each other and turn 1/4 or 3/4 will have the fraction switched. This allowed Split Counter Rotate 1/4 to be changed to Split Counter Rotate 3/4, which did strange things to calls such as Recycle.
I need to resolve issues such as these before I start calling it again.
I once wrote up a handout on Fractal, but it isn't on the web. Sorry.
