The Eyes will follow the mouse pointer all over the page.
If you want to play hide-and-seek with them:
Move the mouse out of the browser window and then into it from the other side.
You don't have to resize the browser window to do this. Just move the mouse
up into the browser's toolbars / menu area, then down one side of the screen
keeping the pointer right on the edge, then into the Task Bar area. But watch
out - the Eyes can see the mouse pointer if it strays into a scrollbar on the
side or bottom of the browser window!
The eyes can't see the pointer while it's outside the browser window and will
stop at the edge of the browser window. But as soon as you move the pointer back
into the browser window they'll chase it - even if you move it in on the far side!
