the wall and the invention

On top of the concrete slab is a low rock wall made from a light-coloured sandstone. Before I bought the land in 1985 the sandstone had already been blasted to level the building site. On top of the rock wall are mudbricks made from the local soil. The rocks in the foreground are bluestone from the local Red Hill quarry.

Whilst fitting the sandstone blocks together I thought about a method where several rocks first pass through some sort of 3D scanner then a computer fits them together and outputs instructions to the builder as to the position and orientation of each rock. I'm in the process of taking out patents on the method. I've called it RockSolver. Have a look at www.rocksolver.com
