Add Floating Hover Text - Which Trails Mouse Cursor

If you want to show any text like "Welcome Here" or "Sign My Guestbook", which follows the mouse cursor (trail text effect), like the one displayed in the image, or in this demo.

Then, simply add the code in any HTML/JavaScript widget (Log in -> Layout -> Add a Gadget).

If you want to show this effect only in the HomePage or any specific page, then you should read this post, on "How to display a widget only in a specific page in Blogger".
