I've been using mynoise.net regularly at home and at work to help me relax or concentrate. It's surprisingly effective, especially after you've calibrated it to your hearing/headphones.
The basic concept is surprisingly simple: each generator is actually a collection of 10 looping sounds, each ostensibly covering a given frequency range. You can achieve really different resulting sounds my adjusting each channel. See for example the different presets (on the middle right of the page) for the Crystal Stream generator. [1]
I'm impressed by the quality of work that Stephane Pigeon put into each of these, and I'm glad he's marketing it well with rain.today :)
