2015-03-09 Marco Haschka did a ChaosSeminar on turtle graphics [0] today at Ulm CCC. More interesting than the actual topic was his editor: A self written line editor. I hope I'll learn more about it some day. It was just so cool that he used a line editor ... in these days! I thought line editors would have vanished from practical use already decades ago. But no, I saw one in action today! :-) [0] http://ulm.ccc.de/ChaosSeminar/2015/03_turtlegrafik http://marmaro.de/lue/ markus schnalke
