We can thank a Jim Henson Company puppeteer for some of Valve's best animation work
The distinctive character animation found in Valve games, such as Portal 2 and Team Fortress 2, owes a debt to puppeteer Karen Prell, who previously worked for The Jim Henson Company. Prell, known for her role as Red Fraggle and puppeteering the worm in Labyrinth, brought her expertise in bringing characters to life to Valve, significantly influencing the animation of characters like Wheatley.
