“Leftover material from the Carpenters” is what I saw in a carpentry room where woodworkers had cut off all the useful plates and discarded some of the remaining strangely shaped wastes. When you pick up these wooden blocks and make them 5 times with a sculpture, you suddenly find that it is also a shape, which forms a space by itself. We originally could not see this invisible space, it was ignored. As all our energies are now focused on how to solve the problem, the wider space that we cannot see is discarded by us.
