Up is a much stranger direction than down
Falling looks normal because you’ve watched things fall your whole life. Watching a search box rise slowly toward the top of a frame and press against it does not look normal at all, and that mismatch is the entire reason this one works.
The heavy things rise slower. The small dots go first and get stuck at the top while the logo is still halfway up, which is exactly backwards from how a real ceiling would sort them and nobody notices.
Grab something mid-float
Click and hold any piece while it’s drifting and you can drag it wherever you want. Let go and it resumes going up from wherever you dropped it. Pull one down to the floor and watch it climb again from scratch, which is oddly compelling for about four minutes.
Three modes
Straight float pins everything to the ceiling and leaves it there. Bounce gives the ceiling some spring, so things arrive, rebound, arrive again, and slowly settle. Zero gravity kills the pull entirely and whatever was moving keeps moving until it hits an edge.
Zero gravity is the one to leave running while you read this. The layout ends up in configurations no designer would ever approve.
The obvious opposite
Google gravity is the same code pointed the other way, and it’s the more famous of the two by a long way. Grogu google lifts things but holds them in mid-air instead of letting them hit anything. Google gravity black hole pulls sideways into a point.
For a push rather than a pull, google fan blows the whole layout off the right edge. The complete set is on google easter eggs.
