Bicycle Blur by Mathieu Bich and Garrett Thomas

This video is a promotional piece for Bicycle Blur, a new illusion created by Mathieu Bich and Garrett Thomas. The effect plays with the audience's perception of focus and blurriness, aiming to create a moment of genuine astonishment. The illusion involves presenting a deck of cards, initially appearing clear, then subtly altering vision to make most cards blurry while one remains sharply in focus. The creators emphasize that it's about the audience *experiencing* the blurriness, leading to a more impactful illusion. Bicycle Blur is presented as a 'utility device' with multiple versions, featuring high-quality cards and a carefully considered design. The creators highlight leveraging the way our eyes perceive focus and depth, creating an illusion that feels personal and disorienting. They suggest the effect's strength lies in the audience's reaction, eliciting bewilderment rather than analytical inquiry, making it a worthwhile addition to any professional magic show.
