- After a lot of messing around, I discovered that using |x| is not the same
- as abs(x) in Fractint formula files. In any case, I finally managed to get
- a Fractint formula for the fuzzy logic image from the February 1993 issue
- of Scientific American:
-
- -----CUT HERE-----
- fuzzy {
- a=real(pixel), b=imag(pixel):
- x=1-abs(a-b), y=1-abs(b-1+a), a=x, b=y, sqr(abs(a*a)+abs(b*b))<=p1
- }
- -----CUT HERE-----

- To center this on your screen use the command corners=-2/3/2.5/-1.5

- Enjoy!
