I am sure that there are stacks of 15 to 20 years old, which show information about an object in a field while the mouse moves over that object. There must be examples of stacks using the mouseEnter and mouseWithin messages for this purpose.
Two examples are a library stack and a contact database, which I started to build about 18 years ago. The library stack was available for download for a while.
The two stacks had so many fields, that I deemed it necessary to add another field, which displayed information about the object that the mouse was hovering over. This had nothing to do with animation, though
The library stack contained a possibility to include pictures and movies, but hovering over an object was not a way to access these pictures and movies.
I am sure I have several old stacks, which show some kind of animation in response to aforementioned messages. If I find something that does what you are looking for, then I'll post another message here.
Best,
Mark
I just can't imagine that such a patent would be enforceable.
