I don’t quite understand what you mean by “Glyph,” nor am I certain of what you intend your GUI to look like, but I’ll try to reason as best I can:
Is it that you want a string of text to loop from its first character to its tenth character over and over again?
If it is, then I would use a for-loop and some timers. To get a rough idea of how to implement it, here’s another question regarding a typewriter effect. The first answer in the post has some code you can reference (just make sure to click the dropdown arrow, otherwise it may not be visible).
