Daily Brain & Mind — Day 14 (Optical Illusion)
🧠 Stepping Feet Illusion (Fast and Slow)
Watch the blue and yellow rectangular blocks glide across black-and-white stripes. Do they move like feet taking alternating steps, or at a steady pace?
💬 What did you see: a robotic stroll or smooth gliding? Drop your verdict below! (Solution in first comment 👇)

💡 SCIENCE BEHIND THE ILLUSION:
Both blocks move at a completely constant, synchronized speed! Stuart Anstis showed that motion perception is mediated by luminance contrast. When the blue block hits black stripes (low contrast), it appears to slow down, creating the illusion of walking.
