Unhide desktop icons I recently had tried to make some hidden desktop icons on my desktop following the instructions found here. I am on Mac OS X Mountain Lion. I ended up somehow making every file a hidden file. The files are all visible but are just transparent and I cannot open some of them. 

How do I make all of these files become unhidden files so they are no longer transparent and I can access them better?
You might have accidentally show the hidden files in Finder. Try this command to hide all the hidden files:

defaults write com.apple.finder AppleShowAllFiles -bool NO


To show it again, change the BOOL value from NO to YES:

defaults write com.apple.finder AppleShowAllFiles -bool YES
