Daily Brain & Mind — Day 3 (Optical Illusion)
🧠 The Café Wall Illusion (Straight or Crooked?)
Look at the horizontal lines between the black and white staggered bricks. Are they completely parallel or tilted at steep angles?
💬 Hold a ruler or the edge of a paper against your screen. Were you convinced they were crooked? (Solution in first comment 👇)

💡 SCIENCE BEHIND THE ILLUSION:
The horizontal lines are 100% straight and parallel! Discovered in a café in Bristol, the border contrast between the offset tiles stimulates localized edge-detectors in the primary visual cortex (V1), producing a false tilt signal across each line.
