Neural Flow BG
Neural Flow Background
A canvas-powered animated background built for Framer. Particles flow through a mathematical vector field, producing smooth, organic motion that reacts to your cursor in real time.
Mouse repulsion — particles flee from your cursor within a 150px radius
Customizable trail length — lower opacity creates long, glowing comet-like streaks
Any background color — works on dark and light designs equally
Auto-resizing — adapts instantly to its container on window resize
Retina/HiDPI support — crisp on all screen densities
Zero dependencies — no external libraries required
Particle Color - #818cf8
Background - Canvas background color - #000000
Trail Length - How long particle trails persist (0.01–1) - 0.1
Particles - Number of active particles (50–2000) - 600
Speed - Flow field speed multiplier (0.1–5) - 0.8
Place it inside a frame set to fill its parent container
Layer text or UI elements on top using z-index / stack order
For a subtle effect, increase Trail Length toward 0.3 and reduce Particles to 300
For a dense, dramatic look, set Particles to 1200 and Trail Length to 0.05
