Pine cones (img) - rather fascinating patterns and shape. So tight and solid - almost interlocking sections. Still only a few of the seeds fall out on normal impact - is it because the tree wants animals to pick up and carry the cones away - and either eat or loose the seeds in other parts of the forest? Or are they in the cone as "backup" - when someone comes along and cuts the tree, they'll most likely kick a cone or ten and scatter new seeds all over the place to add to those already distributed?
