Yeah, I think the link posted here is doing little to make lisp popular, especially compared for example to a nice tutorial like the Seesaw example one to build GUIs in Clojure [0]. There, you can see how interactive Clojure is, and how fast it can be to develop stuff. Note that I took this example because it's on the top of my mind, but I am sure similar proves of interactivity can be made for other lisps.
Holy crap, Seesaw looks awesome! See, that's far more powerful - I had no idea that even existed, and now I'm excited to play around with it. This is great!
I don't need a cartoon to sell me on something. I need to see how something can be used.
