90° is a creative vase that displays an intriguing geometry. The Spanish design studio Cuatro Cuatros created “90 °”, a vase-shaped impossible triangle causing a disturbing optical illusion. Depending on the point of view, both ends coincide and make it look like a closed figure. The vase “90 °” is part of the collection “Angles”, an experimental collection of objects designed by Cuatro Cuatros and based on illusion and anamorphic.
