I'm starting to wonder......
Someday (hopefully soon) you may board your time machine vehicle...select your language, then immediately select where you are from, and then immediately answer a series of questions...then head up the ascent, have your picture taken and then the screen remains off for the rest of the ride.
After you pass through time...that crazy worm hole of infinite stars...your screen won't turn on...but rather you will see yourself and others around you in "the future", again this jibjab style animation, projected on the triangles, including some computer projectors of data and facts, maybe some triangles just showing some graphics.
As for Tomorrow's Child....if the triangles are going to just be an elaboration on the jib jab style video....and not projections of children....then I don't see how a new version of that song would come back...it wouldn't be appropriate.
