Everyone is going polka-dot crazy over Louis Vuitton’s collaboration with Japanese artist Yayoi Kusama. A select few of the luxury brand’s retail locations have been turned into a mini exhibition showing off the artist's work.

But the big change you will notice is the signature polka-dots covering the whole building. Check to see how the transformation went down in the time-lapse video above. [freshnessmag]
