Free White and Pink noise generator

Simplynoise.com plays a flash based loop of white and pink noise. The site is dead simple and easy to use and offers downloadable audio files for offline access, but I wish they would add brown noise as well.

These “colorful” noises can be used for meditation, relaxation and working/staying focused in loud or otherwise obnoxious environments. Some even find the noises useful for making tinnitus less intrusive.
