Lichen have always captivated my attention. I started two lichen etchings while at the Dassler cabin. Both are about to scale. I used my magnifier to draw the lichen on the plate. Some species of lichen are incredibly slow growing, gaining only a millimeter per year. To a degree drawing on the plates is like this. Scientists believe that if they can unlock the relationship/chemical makeup and symbiosis that is lichen, they might be able to unlock the cure for cancer. We can hope.
