He has done commercials for McDonalds, Virgin Mobile, and Axiam. As well as music videos for artists MIMS, and Deathcab for Cutie.
Keith has a very prospective way of filming his work, making the final video very surreal.
Another favorite of mine is the music video "When I wake up" by Wintergreen. It goes through the epic failure of the ET Atari game.
