Two-Liner question

[g.wright@tcs.wap.org (Geraldine Wright)]

Someone sent me an E-mail with a question about one of the two-line programs
I posted to this group. Since I forgot to save the message, and therefore
lost the address of the sender, I will answer the question here. The shapes
which are composed of X's are supposed to be footprints walking up the
screen. The clicking sounds are supposed to be the sounds of the footsteps. I
guess I should have given the program a name, so people would have had
advance notice of what it was supposed to be.
