Meditative Pendulum

I love how it’s 2 double pendulum and you can see how initial conditions change future. But menu options REALLY need labeled. And also there needs a way for the second pendulum lines to be drawn too

suggestion: while i have decipher the meaning of the controls, they could be in one of your release notes to help others who may not know what they are. that way there is no excessive user guide intruding in the app’s beautiful display.
