This is the second in a series of collectible ultimate discs with tessellation designs (made famous by M.C. Escher™ in the mid-20th century). The surfaces of the discs are tiled with repeating geometric shapes. This disc has stylized butterflies which are interlocked and fluttering. Because this disc is printed with two different metallic foils, it gives nice effects in the sun.
This disc was made by Internetdiscshop and is sold out for years. I owned this disc some years ago but gave it away.
