At work this week, our high school intern has been attempting to create images of an open and closed black box by using a (very smelly) permanent marker and coloring an old Mac Pro box. When the PI on the presentation who wanted the image wasn’t quite satisfied with the resulting images, I pointed out that I could probably throw something together with Gimp in about an hour… and make it animate. So, if anyone else on the internet is giving a presentation with the phrase “Such and such systems are generally viewed as a black box, but now we are going to open the box,” and wants a silly animation to go with it, have at this one with my complements. (Wait five seconds… it really does animate. Wait another minute and it will close again.)
