Growing feedback bar

[Leisha Wharfield]

Hi, all,

What would be the easiest way to create a bar that grows on the screen? 
Subjects can earn up to 28 points, so a green progress bar will grow 
every time they earn a point. I have 28 bars of various sizes, but we 
want the bar to appear to grow, so I also have a piece of the bar that 
is one-quarter of one point. I want to add it to the top of the bar in 
quick succession so that the bar appears to grow. The problem is 
determining the exact place on the screen to place the little bar piece.

Is there an easier way?
