Actually, yes- you can! Start with simple sine/cosine stuff and add in
wavelets. That is one approach. Also, there are some range tricks you can do
with a function that will blend a curve into a normal. Once you have your basic
forms, they are simply summed in one function.
It can be a little tricky at first, but soon you develop a sense of which
curve will fit in place. Each function can be scaled and operated on, then all
summed to create what you want.
