Subject: [PATCH] voxel scripts

voxelwall is an 8x8 wall made of voxels that transitions from a bright
red to dark blue

voxelsoundwaves was an array of voxels that was manipulated to resemble
an audio scope that responds to loudness and changes its height
depending on the loudness of the audio that the microphone picks up
