"Ovo" is a baby dragon ready to hatch. It can be interpreted alchemically (as symbol for the transformation of matter) or philosophically (as the ouroboros, the snake biting its own tail, symbol cyclical time). Or you might imagine I am in fact working in Harry Potter's Transylvania, with plenty of dragons around to inspire me :)
