0,0 getting moved by a class function?

Hello

I'm creating a "console" of random images, videos, scrolling text, and every once in a while a nike shoe, an iPhone, or a mansion streaks across the screen and snakes around randomly. Then the images, videos, and scrolling text resumes, but everything is offset, like the 0,0 coordinates have been shifted by hundreds of pixels. its so weird, and I've tried to play with pushMatrix and popMatrix, but nothing I do solves this bug.

I tried to paste my code here, but it's a mess. what's the trick?
