- Gum Wall (Wikipedia)
The Gum Wall is a brick wall covered in used chewing gum under Pike Place Market in Downtown Seattle, Washington, United States. It is located on Post Alley near Pike Street, south of the market’s main entrance off 1st Avenue. Parts of the gum coating alongside the walls are several inches thick, and the coating is 15 feet (4.6 m) high along a 50-foot-long (15 m) section. The Market Theater Gum Wall has become a tourist attraction and local landmark since it was unintentionally created in the 1990s.
- Lozenge (shape) (Wikipedia)
A lozenge (/ˈlɒzɪndʒ/ LOZ-inj; symbol: ◊), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and the word is sometimes used simply as a synonym (from Old French losenge) for rhombus. Most often, though, lozenge refers to a thin rhombus—a rhombus with two acute and two obtuse angles, especially one with acute angles of 45°. The lozenge shape is often used in parquetry (with acute angles that are 360°/n with n being an integer higher than 4, because they can be used to form a set of tiles of the same shape and size, reusable to cover the plane in various geometric patterns as the result of a tiling process called tessellation in mathematics) and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards.
