the courtyard to the Quba mosque in Medina needs a mobile cover that protects the audience from the intensive sunlight but also can be opened at night. Inflatable structures outperform any other construction method in regard to lightness.

The geometry consists of an array of intersecting spheres. Ropes keep the membranes in shape and reinforce the structure.

The upper Membrane layer is opac white with very low translucency while the bottom layer is transparent . Inside the structure LED lights can be installed that can change their colour for a variety off effects.
