Actually a pity it doesn't work on the non-mobile; many of my computers have webcams now and it is kinda convenient to have this (and of course, you ought to always be able to bypass the camera as a user. really perhaps it should be part of the file picker itself but lol those things are so overloaded already)
Did you by chance click the JavaScript demo that totetsu posted? That demo uses the JavaScript MediaDevices API to stream the camera, which is different than the original post that is a file picker that opens the camera on mobile.
