After writing the article yesterday about how to restore the show desktop icon, I received a number of emails asking if I could post the shortcut for Flip3D as well, so I've zipped up a copy of that shortcut as well.
To put it back into the Quick Launch folder, open up explorer and then type in the following into the address bar:
shell:Quick Launch
Now just unzip the file and copy it into the folder, and you'll have the Flip3D shortcut back (the one with the real icon)
It seems like many people delete the icons and then don't know how to get them back, which is an interesting problem, since there's not necessarily a good way to restore them otherwise.
