從「Balls to learning how to animate, let's film some parkour!」這篇看到讓人懷念的遊戲，1989 年的《波斯王子》：
Jordan Mechner (波斯王子的作者) 用 Rotoscoping 的方式將他弟弟做這些動作的畫面拍下來，然後確保在電腦上角色的動作是順暢的：
Here's the source frames used to rotoscope the above animation. Don't let the ghostly pallor fool you! Jordan Mechner's brother is in fact quite healthy; he was altered with state-of-the-art Liquid Paper and Sharpie technology to fit the palette restrictions of the Apple II.
Thanks to Jason Scott and Tony Diaz for successfully extracting the source code from a 22-year-old 3.5" floppy disk archive, a task that took most of a long day and night, and would have taken much longer if not for Tony's incredible expertise, perseverence, and well-maintained collection of vintage Apple hardware.
