Konfabulator is a program that emulates for windows quite nicely the widget functionality found in Mac OS X Tiger. While the two systems are not compatible with each other, the end result is the same. You download small ‘widgets’ which display on your desktop. In case the idea isn’t entirely clear, here’s what my desktop looks like with the widgets I use:
I just have four simple ones – weather, a ‘to do’ list, a Flickr photo uploader, and a CPU usage monitor.
On a side note, how cool would a ‘search the library’ widget be?
