Exactly, I also though of 2d3 as soon as I have seen that blog post. I came to know the company since it is linked by the (very valuable, if I may) book "Multiple View Geometry in Computer Vision", http://www.amazon.com/Multiple-View-Geometry-Computer-Vision... . IIRC the company is run by Andrew Fitzgibbon http://research.microsoft.com/en-us/um/people/awf/ , which now seems odd to me since he's a full time researcher at Microsoft. I wander how Andrew's algorithm in the 2d3.com product differs from the one published by the youtube guys in the post.
