Twilight and Ink Spot-- for that matter, everyone in the square---
stared as the strange contraption rolled into sight. It was about as
tall as a pony, three times as long and twice as wide, and covered
entirely in cardboard spray-painted silver. There was a raised conning
tower of sorts near the back. It was lit from within as well as without;
There were portals and windows cut in various places covered in colored
cellophane where the light shone through, and the outside was studded
with blinking lights, apparently abducted from some unsuspecting
Hearthwarming Eve tree. Tubes, dials, gauges and meters studded the
outside as well. Both sides had bright red arrows , one labeled "the
past" and pointing back, one labeled "the future" and pointing forward.
The arrows labeled "past" were blinking---- quite clever how the red
lights illuminating them blinked sequentially, Twilight thought idly.
The finishing touches were two backlit clock faces fore and aft whose
hands, Twilight noted, were spinning backwards, and a spinning bubblegum
machine light atop the roof. Fog billowed out from under the skirting
around the base, and strange bongs, twangs, and other indescribable
noises, like a sci fi foley artist had gone on a bender, emanated from
the two Victrola horns jutting like smokestacks from the roof.
