FiboPlasma - KDE Plasma 6 Wallpaper Plugin

A Fibonacci clock wallpaper plugin for KDE Plasma 6. Uses Fibonacci numbers (1, 1, 2, 3, 5) to display the current time. The idea is from Philippe Chrétiens project.

Features

• Fibonacci clock algorithm - represents time using colored blocks
• 4-color system: base (off), minute-only, hour-only, and both
• Multi-monitor support - displays a clock on each screen
• Customizable colors and gap spacing
• Works on both Wayland and X11
• Dynamic monitor hotplug support

Requirements

• KDE Plasma 6.0 or later
• Qt 6.6 or later

Installation

Install the plugin using kpackagetool6 assuming you are in the cloned directory:

kpackagetool6 --install . --type Plasma/Wallpaper

Usage

1. Right-click on your desktop
2. Select "Configure Desktop and Wallpaper..."
3. In the wallpaper dropdown, select "FiboPlasma"
4. Customize the settings:
   • Background Color: The background color
   • Base Color: Color for unused blocks
   • Minute Color: Color for blocks representing minutes (×5)
   • Hour Color: Color for blocks representing hours
   • Both Color: Color for blocks representing both hours and minutes
   • Gap Size: Space between the Fibonacci blocks (0-20px)
   • Clock Size: How much of the screen the clock occupies (10-100%)

How to Read the Clock

The clock uses 5 Fibonacci blocks (sizes 1, 1, 2, 3, 5) arranged in a specific pattern:

• Each block can show one of four states via color
• Red = minutes only (multiply by 5)
• Blue = hours only
• Green = both hours and minutes
• Gray = not used for current time

Time updates every 5 minutes. For example, if the 5-block is green, the 2-block is blue, and the 1-block is red, that's 5 hours + 5 minutes + 2 hours + 5 minutes = 7:10.

Uninstallation

kpackagetool6 --remove com.example.fiboplasma --type Plasma/Wallpaper
