Snow that piles up on your Windows windows

The maker built a Windows app with a lot of help from Claude Code where snow settles on window edges and the taskbar and falls off when a window is dragged or shaken.

The full story

Snowpane is a Windows 10 and 11 app that makes falling snow appear in front of everything on screen, with depth: large soft flakes close up, small bluish ones far away, and some falling behind windows. Snow slowly settles on the top edges of windows and the taskbar, and breaks off in clumps when a window is dragged or shaken. Clicks pass straight through.

The maker built it with a lot of help from Claude Code because existing snow apps looked like flat white dots. It pauses in fullscreen games, has a battery saving mode and an optional natural weather mode with showers and turning wind. The maker had tested it on only one PC.

It had been in the Microsoft Store for about ten days, with over 100 installs. It is free; the natural weather mode is marked Pro and free for now.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.
