This can never work in practice. First, it seems super simple to do CV in the video, but only because the author already knows what to type there. It will never be so smooth in real life. Next, if you accept that you have to think what you are doing, why not to fall back to OpenCV in combination with ImageWatch visualizer. The good news is that you save yourself one layer of abstraction which hides important details from you, not to mention learning yet another API.

Basically this, although I wouldn't say "it can never work in practice", just that "a boxes-and-arrows UI doesn't actually make CV (or anything else hard) significantly easier".

It's great to start out with and play around with but eventually you're going to want the GUI to get out of your way and just let you edit the code directly. At which point something like shadertoy is (IMO) the best of both worlds.

You are right, there is good application for this tool in education or people who want to quickly test something new. Shadertoy is great and I like it. It is at the right level of abstraction that I need for my current CG knowledge. I can imagine that there are many people who find Live CV very useful and then move downwards.
