How Would You Zellij a Lemon?

We encourage all students from universities within the ARAB region to explore methods for innovative gemetrical explorations of the islamic tiling method known as zellij (زليج).

The exploration should respond to the challenge of applying zellij to a curved surface.

  1. Define a lemon (it may be resized, cut, peeled, morphed, whole or partial ... )
  2. Design a zellij pattern to apply to your lemon (i.e. in 3D)
  3. Graphically demonstrate the underlying geometries both within your lemon shape and within the applied zellij.
  4. Use computer animation to fully describe and document your zellij design and its application to the curved surface(s) of your lemon.

Evalution Criteria

The submissions will be evaluated based on 3D modelling ability, quality in discovering the underlying geometries of zellij and its application to curved forms. In particular, great weight will be placed on the student's demonstration of creativity and innovation.
