Abstract (en)
The object of the invention is to provide blocks or tiles (1, 5, 9) that enable a designer to generate a considerable number of different patterns over a surface area from a relatively small number of block or tile shapes, which invention is met by a block or tile (1, 5, 9) comprising a three-sided figure, each side of which is curved and of the same radius of curvature, two sides diverging symmetrically from a point of intersection with each other to respective points of intersection with the third side, the said two sides being similarly curved, and the said third side being oppositely curved. The two sides (7) may be convex with the third side (8) concave or the two sides (2, 11) may be concave with the third side (4, 12) convex. The upper, or operative face of the block or tile may be plain or patterned e.g. to create a small cobblestone effect.
