On your windows
It settles where it lands.
Snow gathers on the tops of your windows and follows their rounded corners. Drag a window and its snow slides off; close it and the snow falls to the drift below.
Snowhush for macOS
Soft snow drifts across your screen, settles along the tops of your windows and slips off when you drag them. Sweep the drift aside with your cursor.
Try it: sweep the snow.
