Imagine working or living in a skyscraper where the view was always changing.
Today’s invention is a tower building in which the floors themselves act as elevator cars.
The arrows indicate how the half-floor units move. The rate of movement might be one floor height per day, so that everyone gets a chance to occupy the penthouse occasionally. This would equalise the pricing for occupants (although it would be a costly building to construct and maintain).
In the event of an emergency requiring evacuation, each of the half-floor units could collapse vertically to say a 1m high crawlspace and the elevator mechanism would then bring all the floors to within jumping distance from the ground.
(Obviously there would need to be an elevator of the conventional kind, for daily use, but that is not shown).
