Kernel Rain

Kernel Rain

Cinematic digital rain for your Mac, built from independent streams of custom glyphs that fall, flicker, and fade at their own pace.

Every Stream Has a Life of Its Own

Independent Motion

Columns vary in speed, size, launch timing, symbol cadence, brightness, and trail length for an organic layered field.

Long Luminous Trails

Turn tracers on or off, then shape their length and brightness from compact ribbons to lingering streams.

Custom Glyph Atlas

A distinctive 135-symbol set keeps neighboring characters crisp and separate while streams continuously remix their patterns.

Smooth 60 FPS Flow

Subpixel animation and depth-scaled motion keep the fall continuous across both Apple silicon and Intel Macs.

Black or Current Screen

Start over deep black, or layer the effect over a dimmed snapshot of the screen currently in view.

Atmospheric Effects

Choose signal green, ice blue, ghost white, or amber, then add head glow, analog flicker, and micro-glitches.
