What you are seeing here its a paracetamol molecule : 
. https://en.wikipedia.org/wiki/Paracetamol
There are many candidates for such artwork, dopamine,aspirine, serotonin, amoxicillin ... Many molecules which would also be meaningful to the project. And i may try to fit them later. But paracetamol its symbolic, because it is very cheap, and its also very beautiful when drawn this way.. So be free to suggest me any cool molecule with an hexagon in it .
