The documentary Martino Unstrung is apparently still in post-production. From the production company Sixteen Films:
The human brain; three pounds of jellified fats, proteins, sugars and salts - a matrix of robotic cells housing a myriad of intricate machines. Stare hard at that machinery and you see... well that's all you see. Machinery. That's all there is. But look at the spirits bubbling up from the sludge. Look at the carnival of consciousness flowing from the void. How is this possible?
