A GitHub blog, usefull to me, hope the same for you.
All started with the Coding Train and David Shiftman’s tutorials.
The P5.js online editor is great for starting some animations an you can make cools things easyly. The subject I used are my son’s school drawings about emotions. I scanned and underlined using Inkscape to get an SVG format image. Later I was able to add a fire effect shader for the backgroud thanks to shadertoy contributors.
Below another site where you can share your programs. I published one that was using the fire shader, but get zero likes ! :(
