While we are on a roll of design related posts - one of the cool things from my European holiday was picking up one of the Ty Nant bottles of water while in London. As soon as I saw the Ross Lovegrove designed PET bottle I had to grab some. I have been using it ever since with refills and it is sitting proudly next to me right now. Some more info at the TurnkeyProduction blog.
