I found this impressive tutorial on Youtube on Javascript animation using HTML canvas.  I implemented the code in Outsystems for demonstration.  You may also use the Web block for your own project.

Here are parameters of ParticlesText Web block:

* elementId -- After dragging the web block on the screen, publish it and use the Element Id as the value

* width -- width of web block

* height -- height of web block

* textToDisplay -- text to be rendered by particles.  Default is "CDR"

* colorHex -- Hex equivalent of the text color

Please check the demo application on how it was used.  Any suggestions for improvement are very welcome.
