An interactive control panel for the background vector field. The controls panel opens automatically on this page — press \ to toggle it on any other page.

The field is built from three octaves of simplex noise at different spatial scales and drift speeds, creating weather-like dynamics. A fourth noise sample controls the intensity (length and visibility) of each arrow. Move the mouse to create a vortex.
