A stylized PCB with glowing traces where streams of electrons flow between chips along Manhattan-routed pathways. Each trace is precomputed as an arc-length lookup table so electron sprites can travel at a visually constant speed across multiple right-angle segments, and additive-blended glow sprites stand in for real electron particles. The board surface itself is a single procedurally drawn canvas texture combining a faint grid, randomized silkscreen traces, solder pads, and label rectangles.
