Raid frames are not Nymbia. They are some Ace type frame as to which one I am not sure but I am going to guess and say they are
AceLucenFrames .
The bar across they top is FuBar which can be found on this site. I am not seeing any cooldown count at play in the screenshot, so I will assume you are asking instead about the timers below the buffs. To my knowlege the only timers that function that way and not like the standard Blizzard ones are
Telo's.
Hope this helps. Whoever that druid screenshot belongs to has a pretty nice setup, nice simple and effective.
