Las Sillas by Ludus Ludi is a deceptively simple stacking game involving 15 tiny chairs of archetypal design. Spanish atelier Ludus Ludi (Game Games) specializes in games without rules that invite us to engage in pure play. By seeking to defy the laws of physics and express our deepest sculptural impulses, the gameplay can be an absorbing pastime that perhaps bypasses our intellect, to afford us a deeper exploration of our own natures. However that turns out, the results are as hauntingly beautiful as they can be challenging to construct. Extra chairs are available from Ludus Ludi, and they would love to consider photos of your creations to publish on their web site.
