click the green flag set the value for R, P, r, C then click on Redraw some interesting curve R100 | r40 | P-36 | C2 R60 | r15 | P-15 | C2 R60 | r-15 | P45 | C2 R75 | r-25 | P85 | C1 R35 | r-15 | P60 | C3
the curves are made using the following parametric equations x(t)=(R+r)cos(t) + P*cos((R+r)t/r) y(t)=(R+r)sin(t) + P*sin((R+r)t/r) in the script theta is the variable for t If you find any interesting curve please post a comment with your parameters
