text animation

Hi
I´m trying to create a jitter patch to animate text. Many single letters and words should randomly appear and disapear.
I tried around with jit.gl.text2d and i got something working, but i am afraid i did it in a smart way.
I would like to modify the amount of letters/words, random positions, size of the font, and the length of appearing/disappearing.

Also the text should be readable out of a buffer, maybe coll, but i could not get it to work.
And it should work for many letters/words like a swarm adjustable from few to many.

This is quite a list of needs i hope you excuse.
Can anybody help me with a rough patch/explanation.

Thank you so much

Best
