So far “My other computer is super” is winning, but only by two votes. Close behind is “I (spork) HPC” followed by “I (penguin) HPC.”
My own favorite, the viking helmet, is way back in the also ran pack with the walrus.
Keep those votes coming! I wasn’t very specific before, but the winning design will be on a white 100% cotton short sleeved t-shirt (no pocket).
