Stroboscopic Motion

A discrete series of snapshots that the brain stitches into smooth motion.

🧐 What do you see?β–Ό

A blue ball jumping across the screen. Does it look like it's teleporting or moving smoothly? Depending on the flash rate, your brain might interpolate the path.

🧠 Why this worksβ–Ό

Stroboscopic motion relies on visual persistence and the brain's motion processing areas (V5/MT). If the time gap between flashes is short (under 100ms), the brain prefers to see a single moving object rather than multiple appearing/disappearing objects.

πŸ§ͺ Try variationsβ–Ό
  • Look away: Track the motion with your eyes versus staring at the center. Tracking often makes the motion feel smoother.
❓ FAQβ–Ό

Is this how strobe lights at parties work?

Yes! In a club, a strobe light flashes so briefly that you only see people in frozen snapshots, creating a jerky, robotic motion effect.
