Window curtain that folds up into a geometric shape because of triangular folds on its surface. In letting in more light, the 2D surface of the curtain becomes a 3D shape - like a flower blooming.
The triangles fold in on themselves as the curtains are drawn either horizontally or vertically. The curtain itself can be collapsed into a very compact ball in the corner of your window so that it is almost completely removed from the view.
