🟦 Box Breathing Tray

A lightweight Windows 11 system tray application that animates the classic box-breathing pattern — a dot travels around a square, spending exactly 4 seconds on each side (inhale → hold → exhale → hold), all visible as an animated icon in your taskbar notification area.

Building from Source

Prerequisites

• .NET 8 SDK (or later)
• Windows 10 / 11
• (Optional) Inno Setup 6 — to compile the installer

Steps

# Clone / download the source, then:
cd BoxBreathingTray

# Build + publish (produces a self-contained single EXE)
.\build.ps1

# The exe will be at: .\publish\BoxBreathingTray.exe
# The installer (if Inno Setup is installed): .\installer\BoxBreathingTray_Setup_1.0.0.exe

Or manually:

dotnet publish BoxBreathingTray.csproj `
    --configuration Release `
    --runtime win-x64 `
    --self-contained true `
    /p:PublishSingleFile=true `
    --output publish

How the Animation Works

Side 0 (top):    dot travels LEFT → RIGHT  (Inhale)
Side 1 (right):  dot travels TOP  → BOTTOM (Hold)
Side 2 (bottom): dot travels RIGHT → LEFT  (Exhale)
Side 3 (left):   dot travels BOTTOM → TOP  (Hold)

At the default 4 s/side the full cycle is 16 seconds, matching the box-breathing (4-4-4-4) technique.
