Turn all windows transparent in Mavericks I have been looking around for over an hour now trying to find some way to make all my windows somewhat transparent / translucent ...

I found the app Afloat, however that app doesn't work with all other applications, only some

Any ideas on how I can turn all my windows semi-transparent in OS X Mavericks?

Thanks!
You cannot change the window colors in Finder itself. However, there are finger alternatives that can do this. Try Pathfinder by CocoaTech. I believe it has the option to make Finder windows transparent.
