This is an example of a virtual space,

where the 'Game of Life' it's happening.

The sound you are hearing is from pixel lives,

they develop and eventually die.

The feedback you hear is from your device's chassis

try tapping the back of the device or interact with the microphone,

the sound you hear is alive and unpredictable,

exactly like the game of life you are watching.

Also try put two devices with this webpage running close to each other,

you'll find the two universes will try to comunicate.
