🏁 Scintillating Grid
Move your eyes around the grid. Do you see dark, ghost-like dots appearing inside the white intersections? Use the slider to change the block sizes!
Grid Size: Medium
🧠 Lateral Inhibition
This happens due to a neural process in your retina called Lateral Inhibition. When a photoreceptor cell in your eye is stimulated by bright light (the white dots), it sends a signal to its neighbors to "quiet down." Because the intersections are surrounded by so much white (from the gray bars), the brain over-corrects and perceives darkness where none exists!
