In an attempt to become more productive, I just reinstalled Yahoo! Widgets here at the office to utilized some of the calendar and todo widgets. While search through the widget gallery I found this that lets me log into my Sirius radio account and stream channels to my work PC.
This has got to be the coolest widget ever.
This widgets supports the Artist Seek so I can make sure I know when my favorite artists are being played and even has an alarm clock feature built in.
