Packing table

1asset packing_table "Packing table" complexity=5
2// the toy factory's sturdy wooden packing table, front +z: a pale birch top 4.6 x 2.8 m at 0.82 m on chunky oak
3// legs, a soft lilac tray with a low rim over the left half where the toys wait, a big painted arrow pointing
4// over to the yellow corner brackets of the box spot, flat cartons stacked on the shelf below, and behind the
5// left end a candy-striped funnel hopper on legs whose chute slides down onto the tray. Toys pop out of the
6// hopper's dark mouth; it hums, its crank turns and its lamp pulses, and `drop` bumps it
