This is the one I had a easy time converting to PB but could not get to run in FB. I'll admit, I didn't try very hard but with QB to PB, there isn't much trying. Too long ago to recall what the problem was with FB other than I believe it compiled by refused to run. Just froze on the screen.
Anyway, the code here is for QB, so it works and this is one of the best effects Kris created in my opinion.
I'm not sure what you could come up with in screen zero other than replacing all the little circles with asterisks. That might look good.
