I'd be interested to hear from other LessWrongians if anyone has bought this and if it lives up to the description (and also if this model produces a faint noise constantly audible to others nearby, like the test belt); I'm the sort of person who measures everything in dead African children so $149... I'm a bit reserved about even if it is exactly as awesome as the article implied.

On the other hand, the "glasses that turn everything upside" interest me somewhat; my perspective on that is rather odd- I'm wondering how that would interact with my mental maps of places. Specifically because I'm a massive geography buff and have an absurdly detailed mental map of the whole world, which I've noticed has a specific north=up direction. Obviously those glasses probably won't help shake the built-in direction (if I just get used to them), but I'd still be interested to see what they do.
