Tag posts that received reputation points?

[ludachris]

Is there an add-on that adds a simple icon to each post that has received reputation points? I'd like members to be able to distinguish between posts that have received reputation points, positive or negative, and posts that have not. If a post receives negative points, it can display a negative graphic and if it has positive points, a positive graphic - I know there would have to be some calculations done in that scenario. Maybe just something that represents the last points given, whether it be positive or negative.
