Rocksolver Software for Sustainable Construction

I was building a house in Tassie, partly from the rock rubble lying around the building site. Packing irregular shapes together to form a nice-looking regular structure was hard work and I thought, “A computer can do this.” I realised that as well as solving an intellectual problem, the software would enable the use of a local resource, unprocessed quarried rock, which is about 10% of the price and its production results in just 10% of the greenhouse gas emissions compared to manufactured and processed masonry material like concrete, brick and dimension stone. So, great for sustainable development.
