How does one go about making a metro style tile or icon for applications? As things stand right now the Metro UI looks like an absolute ghetto mess as soon as you get any number of standard applications installed. There is a handful of nice looking tiles, and then a vast number of tiles that are pretty much blank other than an old style windows icon in the bottom corner. Is there any way at all to customize programs that have been pinned to the UI? Or are we stuck with having bad looking tiles all over the place, or none at all?
