Quote:

var a := 80.0
var b := 60.0
var c := 30.0
var cl : int

function hyp (a, b : real) : real
result (sqrt (a ** 2 + b ** 2))
end hyp

for x : 1 .. maxx
for y : 1 .. maxy
cl := 15 + round (8 * (
(1 + sin (
+ (sin ((x + y) / a))
+ (sin (y / b))
+ (cos (hyp (x - maxx div 2, y - maxy div 2) / c)))
)))
drawdot (x, y, min (31, max (16, cl)))
end for
end for

i don't understand this part

cl := 15 + round (8 * (
(1 + sin (
+ (sin ((x + y) / a))
+ (sin (y / b))
+ (cos (hyp (x - maxx div 2, y - maxy div 2) / c)))
)))
drawdot (x, y, min (31, max (16, cl)))

Well obviously. Who'd you get the code from? Why don't you ask them?
