SPIKY TEA BOWL

Sen no Rikyū, the great master of wabi-cha whom Koga admires, is said to have used black tea bowls to erase their own presence and let the tea itself stand out. Moved by this, Koga instead advocates "anti-wabi-sabi" — deliberately heightening a work's presence.

One answer Koga arrived at was studs.
"As the smallest unit of force, I found it an interesting shape — one that acts on sight, touch, and even taste."
