Box Emitting Images
These are the different versions I experimented with before the final idea. Color to represent sound was changed for transparency with a texture mapped feed from the camera. The texture mapping was dropped in favour darkness (alowing continuity with the decoded tape - mapping images on to the recording would have taken enormous space). Emitters were changed to react to differences in brightness as opposed to just the presence of darkness. The boxes being burnt darker was then introduced over meter data at conception.
