I've designed a Windows 8 app that can be used to convert images into Excel mosaics.Its my first foray into Windows Store apps... so feels a little bit of an experiment at the minute. And I suspect not one that will allow me to quit the day job just yet!

Other than just the obvious novelty factor, are there practical uses I could put this to?
