During the Euroshop Retail Trade Fair that took place in March 2017 in Düsseldorf, the exhibition pavilion of German spatial design agency Designplus was open to the public for five days.
The design consists of six archetypical rooms mounted on two circular platforms but there's a twist: every twenty minutes the center ring rotates 60 degrees. This creates six surprising new scenarios, hence the nickname 'Crocopotamus' after the children's book by Mary Murphy.
