Sorry, I didn't explain very well the definition since i wasn't sure if that was what you where trying to achieve. Yes, you can use the polyline with the same structure or you could use the line component but the structure of the definition would change. .....ooops, I didn't save the definition, i'm going to try to remember what i did: The abcd expression formula was something like 'a*b/c*d', i think. The expression component with 2 variables simply checked if the point was inside the circle and returns true or false, but the integer parameter converts true to 1 and false to 0. To do multiple circles, i think you've got to get the resulting list of points after they've been modified from the first circle and do everything again for the second circle (duplicate all the components until the 'move' component). I think you can't just blend them all together using the same components because you don't know what radius and vector to use in each point.
