This loop is a plaster bust drawn in six patterns on an 18 px grid. Grey type on black fills the shadows. Going lighter, the cells turn to black slashes on blue, black scanlines on paper and white 0s and 1s on pink. The highlights are pink crosses on pale pink, and black dots on paper fill the background.
Every pattern covers the whole frame and never moves. The bust only decides which one shows through in each cell, so the type runs on along a row and the scanlines stay straight across cell edges. All of it is built from Cavalry's own nodes and filters.
