This is just a fun idea I was joking around with friends about the other day.

I would like to see a mod that grows your beard longer and longer depending on your level.
So you would begin at level one with a clean shaven face, but as you progressed thru the game, your beard grows.
It seems appropriate considering the terrain of Skyrim and the "bearded" themes that have seemed to of adopted themselves to the game.

Not sure how far Skyrim leveling goes up to, but I would assume the longest beard should not be unlocked/grown until within 25 levels of the max. Or the beard unlocking could be quest based. Alternately, battle scaring/war paint could also be unlocked as a bonus. Think of these features as a status symbols among warriors in Skyrim.

Eye color can arguably be linked to good vs. evil choices made in game. For instance, if you were a good character, you might have clear eyes (any color) However, if you were more evil, your eye color might change. (Red, Orange, White, Black, Reptilian) Think: When Anakin Skywalker turns to the dark side in Star Wars.

Additionally, I would like to see a character sprout from a young child to a skinny young man all the way up to a bulky hairy Nord and then into a old man. What would trigger these changes is up for grabs. Could be quest based, could be level based, could be time based. Same goes for female characters too.
