As a child, many of us toiled away staring at two seemingly identical spot-the-difference illustrations or images to pin point the minor discrepancies. Louis Vuitton and Selfridges have come up with a clever campaign to celebrate the opening of the Louis Vuitton Yayoi Kusama pop-up store inside the Selfridges London branch.

The challenge is to find five differences between video 1 and video 2 below, and it is not as easy as it seems. A dictation of the poem written by Yayoi Kusama, Love Forever, can be heard in the background.
