That's an interesting idea; hadn't considered it.  (The macro just takes a
user-chosen seed value and creates its many random spline values from that.) I
don't exactly understand how I would pull a string of 'different' values out of
f_spotted(x,0,0) to create the spline with; would something like this work?
(Just a general example)...

f_spotted(200*counter,0,0) // counter is just some advancing integer

I.e., translating the pattern a fair distance each count, to get a new 'random'
value each time?
