I wrote an algorithm for the laser that outputs cut and perforation vectors for a folding light tower with almost any dimension.  The tower's top can be removed to expose a place to attach a magnetically fastened LED light and battery.  The starfields require special calculations so that the light finds its way through two folds of paper.
<p>The light cycles through the rainbow.
