Post rating feature?

[the1rabbits]

Hi Guys,

I know this is not strictly to do with vB (it kinda is) but I am after some help or maybe a point in the right direction.

I am looking for a post rating feature similar to that which is seen on the facepunch forums.

See this thread on their forums: http://facepunch.com/showthread.php?t=1258652

If you look at any users posts and your cursor is in their post on the bottom right hand side icons pop up which allow you as a user to give it a sort of rating.

How can i integrate something like that onto my forum? What do you guys use to do something similar to this? Is there a mod of some sort?

Cheers,
thanks for the help guys
