We love these! The 12" diameter discs are a modern, 3-D twist to your typical wall decor. White powder-coated steel would look great against colorful walls or even in a room of all neutrals.
The wall hangings can also be used as room dividers (if you've got the bank to buy several sets). A set of 6 goes for $98 from Chiasso.
