This is a neat way that I have found to get rid of the infamous "I-like-to-drag-and-drop-but-all-the-icons-on-my-desktop-take-up-too-much-space" problem.
It is really just a blank icon: transparent, see-through, nothing there. I put it on all my aliases for dragging-and-dropping on my desktop so that I can get a "list" of these aliases. It's a very nice way of saving space on your desktop.
I made this icon for the benefit of those not familiar with ResEdit or similar utilities.
