I understand that this was meant to be a retelling of how the build process went and what happened afterwards, but it seems quite light on the actual results? I would have liked to see a video demonstrating how well it lets the user see through walls!
"We didn’t qualify for the standard prizes — perhaps spending only 30 seconds on our presentation and lacking a live-demo setup had killed our chances."
That's the result of the competition, but what I want is a demonstration of the actual project: in an uncongested area, take a video of someone walking behind a wall and demonstrate that you can still locate them.
I think the HN algo rewards posts with a high points to comments ratio anyway which is a good thing in this case.
