The purpose of this demo is to test and see how possible is to synchronize sounds with DOM effects while being played in different threads or timers. It looks like, while synchronizing sounds with DOM effects is quite simple and works fine, sounds played by different threads or timers get out of sync after a while.

See the demo in action.

Next step: build a sound controller class that can play sounds at some intervals, delays, etc

I have updated the Grass demo and renamed it to Forest, which I think is a more appropriate environment for the sounds I used. I have done some fixes to the rain loop and I have added some light animations.

Grass is an example of how to create an environment with multiple sounds playing in the background at random intervals.
