Now food can tell you how fresh it is.
This optical illusion image is my favorite from a series by artist Noma Bar for IBM's Smarter Planet ad campaign.
I found this work via a reader's photos of outdoor advertising in Washington, D.C.
See my previous posts 8 amazing optical illusion covers by Noma Bar and 7 "negative space" optical illusions by Noma Bar.
I like me some Noma Bar.
