Potion Vial Upload
The drop zone of an invented spell-pack app, Grimoire, drawn as pixel art and played as the reference recording plays it: a glass vial lies on its side in the dark with a brass-and-steel stopper and an emerald on a gold chain, green smoke curls behind it and a black widow sits on the glass. The file is carried up from its card, the emerald pops off and mist pours out; let go and the file slips into the mouth, the emerald snaps back, a green cloud streams down the tube and the potion fills it as the counter climbs, the spider riding the liquid's edge. At 100 % a fountain of sparks bursts from the mouth, the emerald falls and swings on its chain, and the spider climbs down the chain onto it. The emerald can be grabbed and flung, the spider poked.
