Here's an interesting optical illusion animation I discovered earlier today. Check out them traveling feet on your right: one may think they tend to step out of phase every now and then when the radial grid becomes visible, yet in reality their movement is always constant and parallel. This becomes obvious whenever the grid disappears.

PLoS ONE: Does My Step Look Big In This? A Visual Illusion Leads To Safer Stepping Behaviour

Tripping is a common factor in falls and a typical safety strategy to avoid tripping on steps or stairs is to increase foot clearance over the step edge. In the present study we asked whether the perceived height of a step could be increased using a visual illusion and whether this would lead to the adoption of a safer stepping strategy, in terms of greater foot clearance over the step edge. The study also addressed the controversial question of whether motor actions are dissociated from visual perception

Visual illusions are not only fun, they also help show how the brain works by exploiting its shortcomings. But what about using visual illusions for practical benefit? By making a step look taller than it really is, David Elliott and colleagues have demonstrated a way of doing just that.
