Videos look nice.  I like video 1, although people might think DEERcoin changed its name to iCoin.  Ha ha.  just kidding.  All are good.  font in video 3 could be cleaner.  Video 2 would be awesome, extended a bit, but its obviously going to be the logo reveal for future longer videos, and it will be a very nicely made intro.  Kudos to whoever is putting these together!
