I'm now wanting to set up my magic bullet rig to try this!
Just thinking about consumer equipment, being able to shutter release and fire a laser "burst" precisely enough would be a challenge. If the shutter release is wired, does the time for the signal to travel down the wire + the mechanics of the shutter need to be compensated for the time of flight of the "photon"? I could see this being one of those YouTube channels with someone doing this in their garage.
All of that to say that the accuracy of what they've done is impressive
