What did you notice?

Stare at the cross for at least 15-20 seconds, then describe what you observed. (This is just for you; I don't record it. But it's helpful to be clear about what you saw.)

What's Actually Happening

The Reality

The yellow dots never move and never disappear. They are always there, exactly where they started. Yet you likely perceived them vanishing and reappearing.

This isn't a trick or animation — your brain is actively suppressing them from your conscious awareness.

Why This Happens

Your visual system prioritizes change and motion. The rotating blue dots are constantly changing, while the yellow dots just sit there unchanging.

Your brain decides the stationary dots are "uninteresting" compared to the dynamic motion field — and literally removes them from your conscious experience.

The Philosophical Point

Motion-induced blindness reveals that consciousness actively filters and suppresses information. Perception is not passive reception — it's active construction.

Your brain decides what reaches awareness based on what it considers relevant. Things that are objectively present can be completely absent from your experience.
