A graphical addon, displaying buffs.
Should be possible.

I know Dot Timer can show buffs.
It also gives the option to turn off the Blizzard Buffs.
Some of the totems it just shows once, no matter how many are down.
Others it shows one icon for each totem in place. I know Grounding is in this latter category.

Pitbull's unit frames can show buffs.
It also has the option of making your own buffs larger.

I don't have the expertise to write an addon, but it should definitely be doable.
