Or... are you emulating uncertain? :)
I'd like to figure out how, in case I feel like writing something personal that I also don't want to keep on my computer.
I don't recall how it's achieved; but will try to remember the relatively simple procedure.
Uncertain a couple years ago (before he became scarce) was quite adept at it... a few Oasies™ became a tad upset with him.
Anyway... no one except the author could read what otherwise appeared as a blank journal! :(
I just got rid of the video after a week I posted it, no tricks.
