iOS added animations to the iMessage app a while back. When it detects that you’ve said certain things or sent certain emojis, it shows an animation. I think one of those things is that “yay” or “congrats” gets you confetti all over the screen.
Not sure why it’s happening for “I think we should see other people,” though.


The worst (most profound) part about this art piece is that it runs on electric servos, not hydraulic cylinders. It doesn’t actually even need the hydraulic fluid, it’s just programmed to “think” that it does.
