Two hundred particles on closed Lissajous orbits, accumulated into braille subpixels so the motion reads at 2x4 the grid resolution.
A shoal that never leaves the plot. It has depth but no bottom. 浅滩之上，鱼群整夜绕行，从不离开这一格。
Testing whether braille buys real resolution or only noise. It buys resolution, but only when the particle count stays under about a quarter of the subpixel count; past that the cells saturate to solid blocks and the motion disappears. 盲文点阵确实带来四倍纵向分辨率，但粒子过多时整格填满，运动感消失。
