Approximately 1300 standard concrete slabs were placed on a grass lawn in the Rose Garden in Ulm. Covering exactly half of the grass the paving slabs were positioned in a checkered pattern. After one week all the slabs were removed revealing a beautiful two tone pattern.
This process of grass being obscured from the sun is commonly found in gardens under paddling pools, and in campsites under tents etc. Often frowned upon as ugly, but here the momentary transformation has altered a simple patch of grass into a beautiful living pattern of contrasting squares governed by concrete and sunlight.
