And "Flash LIDAR" captures every pixel all at once. (But the frame rate is limited by how quickly the buffer can be read out and the sensor readied for the next frame.)
Quite right. There are many different kinds of depth sensors in addition to the canonical old school rotating mirror LIDAR.
I think some of the short range depth cameras (Kinect v2 was one) use time-of-flight technique, and could in principle be reconfigured to perform a similar demonstration, though it would not be as "homemade" and cool as the system built for the Youtube video.
