Seeing a unicorn is nothing, but seeing inside a unicorn? That’s magic. Or at least it is in the hands of Alison Woodward, whose macabre but beautiful pop-up “book” Heirloom, which we spotted over at io9, lets you dissect a dead baby unicorn, removing layer after layer of magical tissue. We’ve never seen anything like it. Head here to see the entire project unfold, and then perhaps you’d like to dissect one of Woodward’s birds — there’s a prize inside.
