I'm going to figure out this embedding situation later, I still haven't since I posted my triptych here, amazingly.
Singular screen viewing for the layman, a two-in-one sort of deal.
Separate screens for those who want to project them or get crazy with monitors.

A little blurb about this piece will be written soon...
