JS library for animation of text on matrix display?

Hi,

I am looking for a JS library or JS code to animate text or numbers on a matrix display like on the Espruino Pixel. I am thinking about the following kinds of animations:

1. scrolling horizontal text in a section of the matrix display
   
2. Digits sliding in/out vertically in a section of the matrix display
   
3. Digits/text fading in/out
   
4. Other funny or artistic transition effects
   
   

Does such a library or code already exist?
Where can I get inspriration for funny or artistic transition effects?

The cool thing would be, that such a JS library could not only be used on a LCD matrix display, but also on large LED displays or even within web applications running in the web browser. That opens a wide range of opportunities ...

Just share some ideas with me please.

Best regards,
Wolfgang
