The last cube deals with one of those mysteries that nobody seems to be able to figure out. The achy, breaky heart. I imagined there being a larva in your heart and it grows and develops slowly as you fall in love and get your heart broken over and over again. I mean there is no single meaning to life, so life is just a process like the metamorphosis of this weird heart bug, the germination of that idea or the hatchling guy. So, there you go (Toby).
