Concrete tiles are generally pretty boring, these ones however have a some what interesting twist, when they get wet they transform from plain grey blocks of fake stone to patterned tiles.

The tiles are known as Solid Poetry and were created as a graduation project, I’ve no idea how they work but at least next time the BBQ gets rained off you’ll have something to take your guests minds away from hunger.

More info over at Frederikmolenschot (try saying that after a few pints) thanks the style files.
