Javier Pena Ibanez and Cristina Sanchez Algarra of "Tri-Oh!". created a series of boxes named Cité Surprise, Cité Surprenante which introduce visitors to all of Montpelier’s secret and forgotten places. Viewers become the protagonists as they are able to hide inside the cubes, which are transformed into kaleidoscopes that whisk them away  to all the secret city spots.

This forms part of a growing yet popular form of art known as Anamorphic designs, where ones perception isn't always the true image. Anamorphic art can also be classified as installation art.
