I read the site and it seemed pretty clear? It's a 3d, transparent, high res image of your whole body reconstructed from the wave data from a large number of high frequency ultrasound scans. But it's also a high end spa in San Francisco that softly scans your body. Then, you uh, do as you want with the data (presumably show it to your doctor, who will be perhaps bemused)?
Sometimes I cannot wrap my mind around how funny people can be and how utterly humorless HN has become with its downvoting. @dang this is valid for the community too!
I guess the key quality of the best humour is that everyone can see the humour in it; at least appreciate the joke even if they didn't agree with the underlying point. At best it makes them rethink what they previously thought about the topic. Much of what is offered as humour online (and also mainstream television) is theatrical rage, which generates laughs and applause (a.k.a. 'clapter') from people who already shared the rage, but to those not already on side it just falls flat. That seems to me what's going on here.
