Apsis is the second kinetic sculpture made completely from recycled found metal objects. "Kinetic" means energy in motion. The top part of the sculpture balances on a single pinhead made from a tungsten rod resting on the bottom half of the piece. The two halves are only connected by gravity. There is less than 1/64th of an inch joining the two halves allowing almost zero friction between the pieces. The top piece is very heavy and that's what enables it to spin for such a long time. The spinning motion is designed to wobble giving a whimsical/Madd Hatter sort of feel. All the welds on this piece are hidden, creating a refined piece of rusty, bent-up metal parts...if that's possible. I have left this piece in its natural state, some rusted areas of the base could flake-off over time. I can clearcoat the sculpture upon request but the color will darken.
