Unitframes Health Bar Ticks

[tenub]

I know it's been done in many other games and I'm surprised that I haven't come across an addon / configuration for an addon in WoW like it. I'm looking for something that will show a health bar in a certain number of ticks. For example, it would be composed of 10 squares that each represent 10% of the total health and when the unit fell below 90% the first tick would disappear, etc. Anyone that can help me if there has been something like this released in the past?
