Enter this Spherical Ice Tray Set available at the MoMA Design Store. The set molds two 2-inch spheres that serve as an attractive alternative to everyday ice cubes. One set is enough to fill glasses for you and a friend on the patio, or if you're up purchasing several sets, they could accommodate a larger group for a dinner party or a punch bowl.
Like all of the gadgets available on the store's Web site, you can get the ice trays pictured here for a small discount if you're a member. As a member of the general populace, you can pick the set up for $16.
