Claim Text:
1. A grid structure formed from a plurality of building blocks, the grid structure comprising: a plurality of flat panels, wherein two of the plurality of flat panels are paired in parallel to have one of the two parallel flat panels provide an inner surface to one building block from the plurality of building blocks and the other of the two parallel flat panels provide an inner surface to another building block from the plurality of building blocks, wherein within each of the plurality of building blocks, inner surfaces of the building block provided by any two adjacent panels lie on planes that intersect along a straight line, defined by edges of the two adjacent panels, that passes through an inner corner of the building block, wherein at a location where corners of two or more of the plurality of building blocks meet, the straight lines that pass through the inner corners of adjacent building blocks each lie on axes that have different angles to one another, wherein within at least two of the plurality of flat panels that are paired, the edges of the paired flat panels which are closest each lie on axes that have different angles to one another.
