You sure do mumble a lot. Meaningless shit too.

There is some history to that, I wrote soft for my first IP camera: http://panteltje.com/panteltje/mcamip/index.html The way I hacked that is by looking with 'snort' (monitors IP traffic) at what the web browser with their software did send to it.... They, D-Link, were a bit upset when I reported the security hack/ leak. Anyways when I bought that Chinese x,y cam I added support it. Later I added motion control, wrote a program called 'xipcc' http://panteltje.com/pub/xipcc_setup.gif that can move the camera left right up down. That Linux xipcc code is not on my site, but you can have it if you want, is basically open-source, you could modify it to move the camera auomaticaly, for me it was just a quick hack so I could point the thing. Let me know if you need the code, then I will make a .tgz and put it on my site, is all Linux C though.

Yep On the high end, I have an i-connect picop laser projector (size of a smartphone) that projects color video using rgb lasrs and a moving mirror assembly. https://old.liewcf.com/i-connect-view-x-laser-pico-projector-review-7276/ so I can project anything I want really

I had my first LaserDisc player and when I got my new player since the first was acting up after being in an upright arcade game for a couple years, I took the old one apart because it actually had a nice little light table inside and a HeNe Tube laser and an HV power supply to excite it with. I pumped 60 Hz sine into one and music into the other and made lissajous on the ceiling in my bedroom back in '91. 5 tube 3 inch scope? On the scope face? This was on the ceiling above the laser table.
