Turbo mode (shift+green flag) - or not if you want to see the process. Press v to show/hide a slider for changing the angular velocity of the first wheel w1 (when you press green flag w1 is set to 1). As in the previous project there are three wheels, but now they are in different phases. The values of w2 and w3 are randomized (see inside for details) so there are many different drawings. How many? And how does the value of w1 affect the symmetries of the drawing? In each drawing there are 3600 circles with midpoint on a wheel curve and varying radius.
Inspired by mathematical artist Hamid Naderi Yeganeh's works with circles, see https://mathematics.culturalspot.org/browse and by recent Scratch projects based on Yeganeh's ideas, shared by Selim and others.
