Burn-in prevention

I have been running the breve-creatures screensaver for a couple of weeks now. I do have one concern which is this: screensavers are meant to prevent burn-in. Now in breveCreatures screensaver, the text "Best distance," and "Generation," is always in the same position, which concerns me. Now, I am no programmer, but I have been able to figure out that a lot of the settings for breveCreatures can be found in a file called Creatures.TZ. Can anyone tell me how to modify Creatures.TZ so that when the screensaver is running the text can move around, or switch to a different corner for each simulation, or do something so that it's not constantly in the same place during the screensaver? If you can tell me exactly what to cut out/paste in, that would be great, since I don't know... the language.
Thankyou.
