Tempestarium

Tempestarium is a small pixel-art weather instrument. 

Shape the weather and the sky yourself, choose a preset, or leave it running and watch the weather change over time.

As of now It can produce rain, snow, fog, storms, rainbows, and plenty more sky events. Every sky is tied to a visible seed, so you can copy it and return to the same conditions later. The audio is generated live too. Rain, wind, thunder, and environmental sounds are synthesized at runtime instead of using recorded loops.

This beta Demo includes the complete weather and audio engine, direct weather controls, Quick presets, Today's Sky and Daily Skies, time controls, seeds, environmental sounds, and four curated scenes:

- Rainbow after rain

- Snow under the moonlight

- Pearl-edged clouds

- Storm in the blue hour

Some parts of the interface remain visible but locked in the Demo. Advanced evolution settings, the Sky events editor, Weather Journeys, Rest, Audio-only, Ambient, Companion, and the remaining curated scenes are reserved for the upcoming full release.

There are no scores or objectives. Tempestarium is something to explore, listen to, or leave open in the background while the sky does its thing.

The browser version and downloadable Windows Demo have the same features.
