I got a question about a promotion wallpaper fot the Assassin's Creed. Below the centre of the wallpaper there's a chemical structure of some kind. It contains the elements H (Hydrogen), C (Carbon), N (Nitrogen) and O (Oxygen). Does anyone know what the substance is? It looks pretty complicated. I bet it's some kind of poison.The wallpaper can also be seen on:http://assassinscreed.uk.ubi.com/experience/
