Some may see the illustration move on a horizontal axis while others see it move vertically. This dual-axis illusion is the work of Frank Force an Austin based game developer who has a rather philosophical view about his creation:
The ‘when you see it’ moment is extremely satisfying for this one. Also it is kind of a metaphor for seeing things from multiple points of view, which is more important now than ever.
Check out the video to see if you can figure out which way the illusion is moving.
