At the moment you may have noticed we have a fascination with raw minerals - we have written about them here and in our latest newsletter, but it's this project by designers Joy Charbonneau and Ed Zec that's also caught our attention. They've created a set of cast metal sculptures based on scientific measurements of North America's great lakes. Made from bronze and aluminium, the lakes have been made to scale and are based on bathymetric information from the national oceanic and atmospheric administration. Although it's not raw minerals - the lakes remind us of the stone Pyrite, and it seems the perfect way to marvel at these bodies of water. As shown from top to bottom: Lake Superior, Lake Huron and Lake Ontario.
