sample GIF reactive grid

here is a sample of something i'm working on
as part of my first video performance (with a band...)
i've been working on some ways to have my ASCII drawings
react to sound input. so its nothing really complex yet... 
but potentially could yield some interesting results
although this is a GIF (no sound) you can see a little of what
will happen
the 4 layers
of ascii drawing
grow/shrink/shift
to sound level input
