it's not for ps2, but ps1. Check out N2O, or Nitrous Oxide. It is straight up the trippiest game ever, done by Crystal Method i think?
plasma pong for sure! http://www.plasmapong.com/ it gets hella more intense every level. play it a while before getting high to get a feel for it or else you'll just be tripping balls sitting there

I love Plasma Pong. My HIGHest score is 21. I can't get higher than that. Because the music and the pretty colors just won't stop messing with me.
