About a year ago, Google released their desktop search called Google desktop for Linux. Since then they released some updates to Google Desktop adding support for 64 bit and more file fomats, but they left out one big feature of its Windows and Mac counterparts: Gadgets, mini-applications written in HTML and JavaScript.
With the newest version of Screenlets, 0.1, you can now run not only Python Screenlets but also Google Gadgets, other web widgets, and web applications. If you want to get started with Screenlets, I’ve previously written a guide about installing and configuring it: OS X-Like Widgets with Screenlets on Ubuntu.
