LF Aggro addon!

[Hihobear]

Hiya, I'm looking for an addon that does just (or similar) to this:
http://www.wowinterface.com/download...TankAlert.html
If you're too lazy:
Alerts you when your group members are taking hits.
for example: HealerBear is being attacked by AnnoyingLasher


So far I've only found addons that tells me when I lose threat, either by saying -THREAT- or with help of a colored box around the mob's target. But I don't want those! If HealerBear is being attacked, I want to know it so I can swiftly intervene!
