That sounds infinitely more perverse than I intended it, but it's too late now. Thanks to the talents of graphic illustrator Alexandra Neonaki, showing the geek guy or gal in your life that you heart them is as easy as hitting the gallery and printing out your favorite. I wish I had found these last week, because I would have reenacted kindergarten and given them to all my friends. Well...I didn't have friends then, but if I did I would have.
Of course, I too noticed the formidable absence of one much-loved companion cube from the Valentines, but god knows there are enough cube-obsessed out there that someone else has already thought of that. Oh wait, here you go.
