It started this way. When they mine stones at Lekokoaneng, the throw away off-cuts which become an environmental nuisance.
NUL Scientists took that off-cuts and turned them into sand. Then they used a very ingenious method to turn that sand into the art on this picture.
Everything that you see on the picture is sand. Yes!. Sand!
The framed art was sold for M8000-00. But the NUL Innovation Hub has since stopped making the art, so please don't place requests,.... for now.
