Ok, everyone, I've attached two zip files with several patches in them.
strange attractors.zip contains the patches of interest dglibpd.zip contains abstractions needed to run these patches and many more basic utility abstractions I use in many patches
I also depend on [alternate], probably the only external you'll need. If you don't have it you can probably make do with an abstraction - it has one inlet and two outlets, and when banged, a bang comes out of each outlet alternately. This is such a simple external I don't know why anyone bothered to code it, but it's very useful all the same.
Let me know if you find these patches confusing or difficult to operate - I'd gladly take some suggestions.
Enjoy.
David
