After I stopped laughing at what I was seeing I took several shots of this guy. He turned and saw me and I told him I just couldn't resist the repetition of spikes. He didn't respond in any overt way and I turned away. A minute later I turned back and asked him if he would let me get a profile. He was young and probably a RISD student but already had a cool unsmiling way about him. He didn't really acknowledge my request but within a couple of minutes he began doing what he was doing anyway in profile. Not a word spoken on his part but a very mutual interaction nonetheless.
Posted to the MC03 Masterclass pool as an example of seeing a shot I wanted and finding a way to make it happen.
