Hi Pilou, although it certainly is nice it also takes extra work to generate images like that. You just can't expect that every time someone shares some of their node work that they should be required to do even more additional work if they don't have a lot of time available or if they just don't happen to like to do those extra steps.

If you want to see what it does in a visual way, why not just download it and run it so you can see it right there on your own screen?
