Lay both phones face down on it, and the two little figures lean in until their heads touch.
Two figures sit side by side at the back of the tray, eyes closed, with 0.5 in of air between their heads. Nothing is on the seats, so nothing moves.
Each figure rides on its own long seat, and each seat turns on a pin at either end. The thin lip along its inner edge is where a phone will press.
A phone, drawn here as an outline, goes face down across the seat: one long edge on that inner lip, the other on the frame's rail.
The phone's weight lands inside the pin, so the seat rolls 11° toward the middle and its figure leans in. The other one keeps sitting up.
Put the second phone down and the other seat rolls too. At about 9° each, the two heads meet in the middle.
Pick a phone up and the seat's own weight, which sits just outside its pin, rolls it back. The figure sits up again and waits.
It measures 7.0 × 8.5 × 2.9 in and weighs 4.7 oz: a smaller footprint than a sheet of letter paper, and light enough to move with one hand. Keep it where the phones land at the end of the day.
Nothing joins the two seats. One phone tips one figure 11° toward the middle, and the other keeps sitting up, waiting for a phone of its own. Only with both phones down do the two lean together, at about 9° each, until their heads touch.
Try it: put a phone down on either side.
Both phones up. The two sit apart.
Two phones down. A little closer.
Neither. Nothing in it is powered: no batteries, no cable, no charging pad. The figures move only because a phone is lying on their seats.
Each seat turns on a pin. A phone laid face down rests on the seat's inner lip, inside that pin, so its weight rolls the seat 11° toward the middle and the figure on it leans in.
The seat itself. Its own weight sits just outside the pin, so with the phone lifted it rolls back until it lies flat and the figure is upright again.
Yes: it tips the figure on its own side. The two seats are not joined, so each figure answers only to its phone. It takes both phones down for the two heads to touch.
It is made from PLA and weighs 4.7 oz in all. The phones are your own; none come with it.
