As a teen I made a movie with Arnold, Stallone, and Chuck Norris doing a commando raid together by copying and splicing scenes from their movies using two VCRs and then dubbing over the audio with a Casio keyboard that could make samples a few seconds long. It was actually pretty cool for what it was but I wonder what I would've made with today's tech and youthful exuberance. Or if I had today's computers instead of a Commodore 64.
Do you still have the movie, and if so, can you post it?
For me, I felt old when I went to my first anime convention back in 2002; I was in my thirties. When I saw how old all of the attendees were, I felt all of my 35 years hit me like a brick; I'm the old man now (all of the attendees were teenagers.) It was an unsettling experience.
