I was going to mention MTV's Liquid Television animation showcase as a potential inspiration for this.

That link seems partly confirmed since they mention an online predecessor called Stick Figure Death Theatre and the Liquid Television segment (which re-enacted famous movie scenes with stick figure animations) was called Stick Figure Theatre.

Pretty much each individual segment of that show was mind blowing (it launched Beavid and Butthead) but the stick figure interpretation of Night of he Living Dead stuck with me for years.

YouTube has a compilation: https://youtu.be/-M7-Sew5aU8
