I'm discovering the wonders of ACEOs as a study break/anatomy study. My favorite place to study on campus has four dino skeletons (well, gorgosaurus, archelon, xiphactinus and platecarpus), so naturally inspiration is running on high. Plus I'm studying Chordates so expect more anatomical stuff. Oh oh and they have a freaking gorgeous 2 foot tall amethyst geode, and other thing like pyrite disks and crystals.
