I found the project extremely interesting and the documentary, especially the strategic overview by what I assume is the lead researcher was great. My one suggestion to improve the documentary would be to include a very simple demonstration (3 to 5 minutes), that steps the audience through the reception and processing of a simple signal through one of the simulation systems. I occasionally watch shows about building houses or making candy, they're not always that interesting, but what grabs my attention, the part I remember most, is the demonstration of some simple part of the process.
