It's possible. Use the OnMouseMove event. However, you will likely need two
variables. One variable would be used to control the effect's timing. For
example, when you place your mouse over a button, variable A would be change
to this. However, if you move your mouse 'off' the button (over another
object), variable A would be change--this would control the timing. Looks
like it kind of difficult if you ask me. Cool idea though--might have to
work on this one.
