   Looking for some small C# side projects
  Well, I'm looking for some side projects to do in C#. I was thinking more along the lines of apps that I can use as part of a folio rather than attempting a full game.Some of the things I've done (albeit a while ago):An app to store a .csv full of urls, descriptions and sets of tags that can be searchedAn app to rename multiple directories of files (to change extensions, or add extensions), which I wrote because my previous hard drive crashed and I was left with directories full of files with no extensions.An app to recursively tally the sizes of a directory structure and display it which I wrote long ago before I found better hard drive toolsAnyone have some ideas? They don't need to be revolutionary, I just need some apps to write that would do a task, or make an existing task easier.I'm a little stuck for ideas at the moment.   
  An app that given a set of youtube URLs, will download them all and stitch the videos together? This'll touch on some interop, web fun, some other stuff. Try it.   ;  Would you mind writing a C# collada 1.5 parser?
