Pixel Potion

A flask of glittering sparks that brews, boils over and pours itself back

Thousands of tiny sparks hold the shape of an alchemist's flask over a soft violet and teal aurora. Every so often the potion boils: a luminous stream of sparks curls up out of the neck, drifts across the sky as nebula dust and is drawn back into the glass. Move the mouse and the sparks swarm around it, click to throw a handful, and play music to make them flash on the beat.
