Optical Illusions in Digital Signage

Hygiene Color Bleach Advertisment

I Believe in Adv posted a great static outdoor ad for Hygiene Color Bleach that uses a visual illusion. The ingenious ad created by McCann Worldgroup, Bangkok, Thailand, hints at the product’s efficacy by showing a stain on a sweater from far which disappears as you get closer to it. Click on the image above and try for yourself, it works on-screen too.

I don’t think I’ve ever seen optical illusions in ads (unless you count album covers)—what about digital signage? Anyone seen any creative uses of optical illusions in digital signage content?
