I mostly agree; ideally there would be a prominent link to a 30 second video that does a very quick demonstration of how/why this works. This is an example where video is just way better than text for introducing a concept.
I get that not every repo is going to have a nice readme, but it definitely would be nice here.
A link to an introductory video is the third sentence in the readme :)
"Each letter of the alphabet is an operation, lowercase letters operate on bang(*), uppercase letters operate each frame. Have a look at some project created with #ORCΛ, or some example files. Here's an introduction video. "
