It wasnβt supposed to go this far, but it did. Long past its mission, itβs still out there so far away now that a simple hello takes a day to reach it, and another day to hear if it says hello back

Last post for #FossilFriday this lovely #Proterozoic #Acritarch because I love it so much. This image was taken with a macro lens at 2x attached to a microscope with a 100x mag lens. It's a combination of over 100 images stacked and stitched. #Geology #Paleontology

The pic is a curry comb. The name comes from the french word corroyer (older versions spelled differently that yielded curry). At least from what I have found, it translates to "prepare" or "make ready." As in to make your horse ready, not prepare your curry.

"Butterfly Effect" is by far my favorite piece I've ever drawn. I know I keep sharing it, but I just hope it brings joy when people see it.
(Plus I don't have a whole lot of new art to share.)
