So cool！

A Lindenmeyer System is a grammar with simple recursive rules, which produce strings of symbols that can be interpreted as graphics commands in programs such as Python or Turtle to draw a line, turn by a certain angle, etc. The result of various grammars and ways to interpret them can be quite beautiful fractal images. +Andreas Wilhelm, a German Applied Computer Science BSc. who blogs about Computer Science and Math, has been making art using L-Systems (en.wikipedia.org/wiki/L-system). His blog, avedo.net/554/lindenmeyer-systems-a-python-adventure/ describes his work with plenty of interesting examples. Thanks to +Appropouture for finding the animation I posted here, which he got from verbalairways.tumblr.com. It is Michael Frame's animation from the Yale site on fractal geometry. Information on how it was generated is at: http://classes.yale.edu/fractals/FracTrees/Animations/Animations.html and further details regarding its mathematical properties under Section 8: http://classes.yale.edu/fractals/

吐槽，发给合作方的待填写Excel表，格式极度混乱会给填写人带来巨大的麻烦。仅仅修改表格莫名其妙的格式错误就花去了比填写表格内容更多的时间！

推特上收到垃圾私信，想把发私信的人拉黑，发现……居然不能通过点击发信人头像跳转到他的页面……连复制ID都不行，为什么要这么设计？
