I absolutely love the sound of running water. The sound of running water is very relaxing to me and helps me focus and think clearly. I know they sell CD's with the sounds of water but they're just not the same. There is a nice pottery place in Berkeley that sells these really cool, four foot tall, fountain vases that produce an amazing running water sound. I might settle for something like that but I would much rather just set up a desk right by the river and work from there.
