The more sound you make, the more tangled in a web is the resulting butterfly. Try speaking with a low voice
A butterfly draws a ... butterfly. Minimal version of a more complex but very cool project by Dapontes. Mathematical model has been borrowed from Modellus examples. ---- This is yet another remix (see one from Tziortzioti) allowing you to draw the buttefly faster by making some noise (turn on your mic) to increase the step for the independent variable t.
