Regular Division of the Plane Regular Division of the Plane Regular Division of the Plane is a series of drawings by the Dutch artist M. C. Escher which began in 1936. These images are based on the principle of tessellation, irregular shapes or combinations of shapes that interlock completely to cover a surface or plane. The inspiration for these works began in 1936 with a visit to the Alhambra, a fourteenth-century Moorish castle near Granada, Spain. Escher had visited the Alhambra once before in 1922 but in this visit he had spent several days studying and sketching the ornate tile designs there. In 1958 Escher
Alhambra (board game) promo expansion/module "The Magic Buildings" adds 6 magic building tiles to the game. When drawn, these tiles can be placed to score extra points depending on their surrounding tiles. The promo expansion/module "The Medina Buildings" adds 9 Medina building tiles to the game. During the scoring rounds, they award "negative" points to the player with the fewest of these tiles in his/her Alhambra. The success of "Alhambra" has also led Henn to release or re-release some other games under the "Alhambra" name and Moorish theme: A video game version was being developed by Vivendi Games for the Xbox 360 console
