eXistenZ (1999)
Not so much the story itself as it's quite a familiar idea explored in other sci-fi films but the 'organic' style to everything was so bizarre.
Agree that organic (as opposed to mechanized) "technological" aspect of eXistenZ was unique.
Also, the are-you-in or are-you-out of the game ending was much more original at the time. It is a concept that existed but, as video games and virtual reality were far more a concept than they are now, not in that regard.
I would categorize David Lynch as disturbing.
The weirdest thing I've seen that anyone might know about had to be Akira or from Spike & Mike's animation. Mind-blowing.
