Burning Twilight gives me warm fuzzies.  You’d think it’d be old or too easy by now, but no. It’s delightful.

The word chiral actually comes from the Greek word for hand.  Since chiral is not superimposable, something that is achiral is superimposable.

The chiral concept is pretty straightforward, but it fits in with tomorrow’s comic, which is something I find pretty interesting.  SPOILER ALERT.
