As I recall, the designer of that lock posted to this forum some time ago. I'm to tired to try and pull it up, but a search for Tigr should do it. It's a cool sounding idea, and it does have some advantages over a standard u-lock; a jack won't really do much damage to the design, and taking an angle grinder to titanium produces dramatic results. However, it doesn't provide much in the way of a secure appearance, so thieves may try to steal it, fail, and get mad. I'd fund it if I had the spare cash at the moment, it seems like it could be the right lock some of the time.
