form is used to set the equation crackle uses to calculate the value
of the pattern at any given point.  The default form is <-1,1,0>, which
returns the difference between the second-closest point and the closest
point.  Form takes the distance to the closest point and multiplies it
by the first term, the distance to the second-closest point by the second
term, and the distance to the third-closest point by the third term, then
adds them all up.  Messing with form can give completely different patterns.
form <1,0,0>, for example, gives you something that looks kinda like a 
bunch of bacteria.
