How to install screenlets in ubuntu/linux

Screenlets are small owner-drawn applications (written in Python) that can be described as "the virtual representation of things lying/standing around on your desk". Sticky notes, clocks, rulers, ... the possibilities are endless.

The goal of the Screenlets base-classes is to simplify the creation of fully themable mini-apps that each solve basic desktop-work-related needs and generally improve the usability and eye-candy of the modern composited Linux-desktop.

Features:

• Real applications, no HTML-"widgets"
• Easy to use, easy to develop
• Full compositing support
• Works with any composited X desktop (compiz, xfce4, ...)
• Works also on non-composited desktop
• Included ability to apply themes (SVG, PNG or mixed)
• Fully scalable when using SVGs
• Embedded drag&drop-support
• Automated storing of options (using ini or GConf)
• Controllable through customizable D-Bus service
• Can be used together with compiz' widget-plugin to create a Dashboard-like feature as seen on OS X
• Uses Cairo and GTK2 for drawing and windowing
