It's LOGO I believe. See here.
Here's another example. Most primary schools in the UK used to use this at some point I believe. I used it for programming a little robot than ran around the floor, as did the rest of my class about 10 years ago!
Logo is wonderful because for very little work you can get some great graphical feedback. One of the themes of my class has been demonstrating that some seemingly complex things are in reality created by very simple processes.
Quote above; here's another article that gives some good descriptions of what LOGO is and how to use it.
