Wonderfall 1.3 is a winter update for the Mac desktop app. Snow now settles on the tops of your open windows and moves with them, you can roll snowballs and build a snowman in the snow bank at the bottom of the screen, and a little snowplow clears the snow for you. Leaves and petals gather on windows too, and rain splashes on their edges.

Version 1.2 taught snow to pile up along the bottom of the screen. Version 1.3 makes that snow part of your desktop: it lands on the windows you work in, and you can pick it up and play with it.

Snow settles on top of your windows

With snow accumulation on, flakes now gather along the top edge of every open window, not only at the bottom of the screen. Move a window and its snow travels with it; drag it quickly and the snow slides off. Autumn leaves and spring petals collect on windows the same way, and rain splashes into droplets when it hits a window edge. Wonderfall only reads where windows are, so no screen recording permission is involved.

Roll snowballs and build a snowman

Choose Play in the snow in the menu. Drag along the snow bank to roll a ball that grows as it goes, stack three balls into a snowman with a beanie and a colorful scarf, or flick a ball up to throw it at the screen. A short tutorial walks you through it the first time. The snowman guide has all the tricks.

A snowplow and a leaf sweeper

Clear all snow now sends a little snowplow across the bottom of the screen, and Clear all leaves sends a leaf sweeper. The shovel and broom are still there if you prefer to clean by hand.

Everything else in 1.3

  • Icons next to the items in the menu bar menu.
  • Improvements for setups with several displays.

How to try it

Update Wonderfall from the Mac App Store, choose Snow, and turn on Snow accumulation under More effects. For snow on windows, keep the weather area on Full screen and the display layer on Over windows. These effects use Wonderfall’s Metal renderer. Then add lights and a wallpaper for a full Christmas desktop.
