Working on some tweaks to Foohy’s original Wallpainter app, which allows you to render windows behind the desktop interaction layer (i.e. behind any icons).
I added better support for multi-monitor setups, as well as some options for specifying exactly where to place windows. I also made the window title search more forgiving (before it had to be an exact match).
I’ve been using this (as shown above) for my displaying my music in a non-intrusive way.
