(1) I'm working on simple programming language, like forth, but in Chinese. It may also control a tortoise like logo. Just for fun. http://qinmishu.org/static/wangbalang/repl.html

I think the most important feature that discriminate it from others is "bubble clusters". It is an opensource software, find it in https://github.com/henryscala/suosuoban.
