These almost make me want a tattoo. The watercolor ones are really cool. It sort of reduces tattooing to its most fundamental essence: You're painting on yourself. Having a tattoo that's of a thing means you are burdened with its connotations and significance. This is pure body-as-canvas. Neat.
I recognize that this flitting about is flaky and have decided I don't care. Bikes! Tattoos! The plus side of being easily distracted by nifty things is it saves money---never enough time to invest in such passing fancies.
