Black Box (sjl)

Black Box is a game where you are given a box with some atoms inside, and you need to determine the positions of the atoms by sending particles into box and observing where they exit. Black Box originally appeared in the August 1977 issue of Games and Puzzles. A computerized version in BASIC was included in More Basic Computer Games (ISBN 0-89480-137-6). This version is a port to MakerLisp for the Lisp Game Jam 2019.
