What the snow does.

Snow falls over the apps you already have open. When it settles, you can move it, play with it, or clear it away.

Snow settles on real windows

Snow collects on visible window tops, the bottom Dock, and the bottom of your main screen. Move a window slowly and the snow follows. Move it quickly and some shakes loose.

Roll, toss, and stack

Drag through settled snow to roll a ball. Pick it up to move or toss it, or stack three balls to build a snowman. A quick sweep of the pointer brushes loose snow away.

Clear a path with the plow

Run the plow from Tools. It starts at the bottom of the screen, then clears the Dock and visible window edges. New snow can settle after it passes.

A tour of Settings.

Click the snowflake in your Mac’s menu bar and open Settings. The app puts weather, snow tools, and display controls in three tabs.

Questions about Fulgy.

Compatibility and a few things to know before you turn on the snow.

Will Fulgy work on my Mac?

Version 1.0 is in testing for macOS Sonoma 14 and later, on Apple silicon and Intel Macs. Fulgy runs on your main display.

Can I keep my own wallpaper?

Yes. The cabin is the wallpaper for this demo. On your Mac, Fulgy draws snow over your current wallpaper and open windows.

Why isn’t snow settling on the Dock?

Keep the Dock visible at the bottom of your main display. Under Settings → Snow, turn on Snow Accumulation and Snow on Dock. If the snow sits above or below the Dock, use Dock Calibration in Advanced.

How do I build a snowman?

Hold the mouse button and drag along a drift to gather snow into a ball. Lift it off the edge, then roll two more balls. Place a medium ball on a large one and a small ball on top.

How do I pause or stop the snow?

Click the snowflake in the menu bar and choose Pause or Stop. Fulgy also pauses when a fullscreen app covers the display.
