He uses quite a bit of tooling, including
lasers. It's not like he would be able to get this far in the middle of nowhere :)
In a way it is somewhat similar to people writing demos for old computers using emulators. Still great fun, but using these tools it doesn't take a village to make one floppy disk. With modern hardware you are apparently able to pull this off on your own. That would have been almost impossible in the 1980s, when these floppy disks were popular.
I probably worded it badly, but I really enjoy these efforts, and I would never be able to do this myself, even if I had a shed with all those tools!
