Super cool concept.

Nothing against the iPhone, but it would be neat to also have (e.g. open source or DIY electronics) projects which enabled use of lidar tech at home-user prices.

It's worth noting (again, without trying to be a grinch - merely trying to add to the overall picture) that there are actual dedicated lidar scanners on the retail market, of higher spec and capability, within a similar price range as the Apple devices involved here.

Of course, you don't get an awesome iPhone with those! :)
