A short video to promote the J language

In response to work being done on the J forums in promoting J to various audiences, I decided to take aim at what I think would be a good audience for learning J – middle and high school math students. I kept the video short and focussed on the the utility of J’s use of ratio arithmetic.

If it looks as if this is on the right track, I have ideas on a few more of this style of video to raise the interest of newcomers to the J programming language.
