Run Unity app as Windows Wallpaper/Desktop Background

Hi,
A while ago I was working on an Android app that worked as an interactive Background. Eg it created sparks whenever you touched it . Is such a thing possible on Windows 7/8 as well? If so, how can I embed it? I do not mind if it requires some hacks, as I just want an interactive background to organize my own ongoing tasks.

Thanks,
kiriri
