About the Circuit effect
Circuit fills the screen with a repeating pattern of box-drawing characters: horizontal traces (─), vertical traces (│) and junctions (┼), chosen by a simple modular formula on each cell's coordinates. The formula produces a diagonal, PCB-like texture that tiles seamlessly at any size. On top of that static board, a scattering of nodes (●) blink on and off as a sine wave passes through them, like LEDs or signals pulsing along the traces. Because the board itself never moves, the effect is calm and precise, with life coming only from the blinking points. It suits hardware, electronics, embedded and DevOps themes, and looks especially good in green, the colour of real solder masks, or in cyan for a sci-fi control panel.
