FieldPlay

A simple vector-field demonstration inspired by https://github.com/anvaka/fieldplay.

Each particle is defined by a position and a velocity. For every particle, its velocity is calculated based on the formulas at the bottom right, resulting in many beautiful patterns.

Press "Randomize" to create a new random function.

Press "Color By:" to toggle between coloring particles by their angle and their speed.

Press "Center" to return the viewing center to (0, 0).
