Sometimes a mashup of two existing ideas just makes sense.  For example, let's mash up two of the most popular Windows Sidebar Gadgets (or Widgets) - a clock and a photo sideshow.  After seeing The Human Clock on Time's Top 50 Web Sites it's occurred to me that this would make a great Gadget for Windows Sidebar with a human element.  Imagine a clock that shows original pictures from around the world, each incorporating the time in a unique way.  It should be super-simple to write (I'm just a little busy with other projects right now <g>).  Anyone want to write it (with the author's permission of course).
