Logo hasn't disappeared, though it's evolved a bit. Northwestern University has a version of Logo called NetLogo. http://ccl.northwestern.edu/netlogo/ http://ccl.northwestern.edu/netlogo/ It's a decentralized version of logo, where you can control multiple turtles at once. It's useful in simulating distributed systems, such as "turtles, termites, and traffic jams." There's a book by Mitchel Resnick by the same name. http://books.google.com/books?id=K8P1rX8T4kYC&dq=turtles+termites+traffic+jams&pg=PP1&ots=xjELl6ou14&sig=vbEYZIfpZuAgy9oWsx4zEEn0VbE&prev=http://www.google.com/search%3Fq%3Dturtles%2Btermites%2Btraffic%2Bjams%26ie%3Dutf-8%26oe%3Dutf-8%26aq%3Dt%26rls%3Dcom.ubuntu:en-US:official%26client%3Dfirefox-a&sa=X&oi=print&ct=title&cad=one-book-with-thumbnail http://books.google.com/books?id=K8P1rX8T4kYC&dq=turtles... If you get a chance, run some of the simulations on their demo page. They're available as java applets. It's pretty amazing to see complex patterns stem from simple interactions, also a theme of Wolfram.
