Sargentlard you have a real talent! Better than this guy:
I did a degree in chemistry many years ago, and was particularly interested in organic chemistry. looking back I think that that was because I really liked the visual and spatial aspect of that discilpine. That interest has extrapolated into fine art. I'm not very good at posting pics up, so I'll simply add a link to my on-line gallery.
...except that the board isn't allowing me to add a link :bawl:
I guess that stuffs that, but you can find my gallery by googling 'andy lloyd art'
