Rocksolver is a highly innovative construction technique using software to solve the 3-dimensional jigsaw puzzle of building with unprocessed rock. Tonight on ABC TV's New Inventors program the inventor of Rocksolver, Malcolm Lambert, will introduce the first working prototype.

Rocksolver is being developed by Intresto, an Australian R&D company based in Armidale, NSW. Rocksolver is the first software application of its kind and Intresto's aim is to release Rocksolver as a means to unlock the world's largest resource of sustainable building material, unprocessed rock.
