I'm often considered a conceptual photographer. Probably because I so often solve the problem of, "How do we make a picture about 'that' idea?" So next week I will be making a portrait about this molecular compound. Yes, a portrait.
If you can guess this compound, I will send you an original, "I Hotdog Chicago" t-shirt in the mail.
Congratulations to Evan Sears for the answer: Oxytocin
