I am a mathematician by trade. I love books of all kinds. I have a special reverence for trees and other growing things. I like typography, knitting, origami, making things with cardboard, x-acto, and tape, making and wearing costumes, flying kites, drawing, bicycling, climbing on urban structures, tumbling. I enjoy most things absurd.
