This app is a 3 wheel spirograph. With the 4 seekbars you can control the length (l) and the number of teeth (t) of the wheels.
The formula:
x= l*sin(t)+l2*sin(t*t2)+l3*sin(t*t3)
y= l*cos(t)+l2*cos(t*t2)+l3*cos(t*t3)
If you toutch the spirograph picture, the app will calculate 10000 steps . The pictures can be saved on sd-card into the "Spirograph" directory
