Pelican riding a bicycle

Every time a new model comes out, everyone has it draw "a pelican riding a bicycle" to judge its spatial ability, and it's almost always animated with HTML and SVG. I'm honestly tired of looking at them, so I want you to make the most complex, most detailed, most beautiful animated video of "a pelican riding a bicycle". You can use any technology. There's no rush; you can spend a whole day drawing it.

每次一个新的模型出来呢，大家都让它去画 “鹈鹕骑自行车” 来判断这个模型的空间能力，基本上都是用 HTML、SVG 来画动画。当我实在看得都有审美疲劳了，我希望你能画一个最复杂、最精细、最精美的 “鹈鹕骑自行车”的动画视频，你可以用任何的技术，不用着急，画一天都可以。
