It is a shape you may have seen before – a classic (even iconic) example of a drawn object that cannot really exist, but seems convincing to the eye nonetheless.

Now, viewed from the right angle, this real three-dimensional vase by Cuatro Cuatros replicates that impossible two-dimensional figure, inviting viewer interaction by encouraging people to line up their sight just right.

At other angles, it remains a compelling linear minimalist piece of everyday decor – it would be equally easy to miss the hidden meaning but still enjoy the item’s overall simplicity.

From its creator: “The interposition, orientation and perspective create a contradiction of the space that makes us perceive something that is not. It comes from the Penrose experience. 90 ° is a vase that, based on a drawing, has been converted to a geometrical shape with volume. Depending on the point of view, both ends coincide and make it look like a closed figure.”
