#228Interleaved Gradient Noise

A clean diagonal tonal gradient, gently swelled by a soft travelling wave, dithered with Jimenez’s interleaved gradient noise — the one-line game-engine screen whose faint diagonal weave sits neatly between Bayer’s grid and blue noise’s scatter; a golden-ratio temporal offset makes it shimmer without ever losing its still thumbnail, and the pointer slides the source tone brighter or darker to sweep dots across the whole ramp.
