As your dynamic does not depend on time, the frame number should not enter the computation. The time step is a global constant related to the frame rate. ...

An absolutely positioned element is positioned relative to its parent. If there is no such parent, it is positioned relative to the window, just like in your example. Add z-index to make ornaments and lights ...

Coordinates as a matrix This: x_co = [np.random.uniform(0, 2) for i in range(n_particles)] y_co = [np.random.uniform(0, 2) for i in range(n_particles)] return x_co, y_co is a little baffling. You call into Numpy to generate uniformly distributed numbers (good) but then put it in a list comprehension (not good) and separate x and y into separate lists (not ...
