Sheet of Coal [Wallpaper]

Fancy a skeletal formula pattern on your computer desktop? This one, resembling a portion of coal, can be tiled to give a 'random enough' effect. All valencies have been adhered to, although I have not checked if all of the heteroatoms and functional groups can actually fit. Click through to access the full image.

As a 'Where's Wally?' game, see if you can find the following groups:
  • Methyl (CH3), valency 1
  • Oxygen (O), valency 2
    • The such as a ketone
  • Nitrogen (N), valency 3
    • The such as part of an aromatic system
  • Sulphur (S), valency 2
  • Alcohol (OH), valency 1
  • Primary amine (NH2), valency 1
  • Secondary amine (NH), valency 2
