Pythagoras designed a special cup to teach his students about greed. The cup would hold wine…unless it was filled too high, in which case the wine would be siphoned out the bottom, draining the cup completely. His lesson: moderation begets equality, which begets justice.
This cup's siphon was created by removing a thin slice from the center of the blank, CNC routing a channel, gluing the blank back together, and then turning the cup, careful to not cut into the inner channel. The CNC was also used to engrave the words "Moderation Equality Justice." Walnut and maple, 7"h x 6.5"w.
