Ok, this counts as a Transformers haul.
Long story short, last week, a guy on my team at work was leaving, and moving to Australia. He comes up to while he's cleaning out his desk.
Him: "Yo, you want a Transformers pen?"
Me: "WTF?... Sure, why not."
Basically, you press the black button, and the cover is spring-loaded and "automorphs" in a smooth motion.
I asked him where he got it; he told me his mom owns a toy store here in Montreal (the kind with educational toys for kids, not the kind with TFs or Soul of Chogokin or Hot Toys Movie Masterpieces), and she got this at a trade show.
