TrackSol, is your desktop widget for Windows or for GNU/Linux? If GNU/Linux, somebody could steal parts of the existing code

Also, what I'd be looking for is a kind of "intelligent" photo frame application (may well be a widget, why not). It should pull images from pre-defined sources, online or offline. The images should be taken at the same day and time (in my hemisphere) so they reflect the current season and time of the day. I would see christmas photos in december, and a beautiful sunrise in the early morning...

In a second filter mode, images should be selected by keywords/tags; keywords could be entered manually (boring) or taken from recent posts in selected newsfeeds. This would make the photo application cycle through photos from Italy while my friends spend their holidays there or look for N900-images while it's hot in the blogsphere.

The application should allow me to set each filter exclusively or combine them ("show pictures tagged "italy" that were shot on sept 28th around 8:30").
