I was playing around with coherence mode and thought it might be pretty interesting to totally hide the windows taskbar and launch windows apps from the OSX dock. I created a simple proof of concept system that actually works. You can download it to try it out yourself here: http://www.verysimple.com/blog/?p=67 This is by no means pretty, but it does work. I can see that Parallels might be headed in this direction of making Windows transparent. For now though, this is an interesting way to control Windows through OSX. I don't know how much more time I can put into this , but if anyone is interested, I'm open to ideas and suggestions. I included all the source code as well in case anyone is motivated to take this a step further.
