First of all, bravo to Martin for putting in the time and effort to make that video. I think it does a very good job of showing a newbie why it might be worth learning J. So please---please---take the following criticism as constructive.
Concerning the music: I felt the music's emotional content varied, and that detracted from the video. A somewhat harsher view---add salt to taste---is that music adds nothing to the information content of the video. In that sense, one might view it as the video equivalent of what Edward Tufte calls "chart junk". http://en.wikipedia.org/wiki/Chartjunk How about rounding out the video's claimed 15 minutes (you have 38 seconds left) to, however briefly, near the beginning, say something about J's unusual syntax? I.e., address the "Culture Shock" Henry Rich refers to in his book. In the last example, it would look better if the adjusted date range was persistent (meaning no need to press 'Go' after each change of the stock view).
