Are you thinking of 2d or 3d instruments?

I've thought about looking into pop-up dialogues for 2d 
instruments and animating 3d instruments into a more readable 
position but both of these would require triggering events.

If it were possible to change the mouse cursor as it passed over 
a hot-spot it could also trigger the pop-ups or animations.

Haven't actually tried anything yet, of course...
