>How was this effect achieved?
I done the same research years ago and find out they were using Video synthesizer analog computers the most notable will be Scanimate for these effects in the 60s until the end of 80s beeing slowly replaced by digital computers.
Many 80's intros were done with video synthesizer. Example: The pics related I posted are from Widget the world watcher intro.
>Is it done in a similar way to that?
I don't know precisely how it's done but similar like this poster said >>1037867 Left the area unpainted and shine this area with video synthesizer.
It's possible to replicate these effects with digital computer today but most modern motion artists are just lazybones.
