Does anyone have any knowledge of some example code that would cause random sections of an LED strip to fade to a color and then another random section fade to another color, etc.? I’m looking to create almost a ‘bubbling’ effect. Just poking around here to see if anyone’s already done something similar. Thanks!

These might give you some ideas to explore.

// Test of chasing random target values, version B.
//
// Random target values are generated and assigned to random pixels.
// Pixel brightness is then increased or decreased toward the target.
//
// This version incorporates a hue shift based on the pixel value.
// The high and low color choices can be changed below in the variables.
// Saturation is kept at full, but it could also easily be tweaked.
