Over the years Jim Henson created great series of muppet sketches that explore the process of “visual thinking”. It started with an episode of “Sam & Friends”, Henson’s first television series, where Harry the Hipster gives a lesson in visual thinking to an early version of Kermit the Frog.
Jim Henson then did a remake in 1966 on The Ed Sullivan Show, transforming Kermit from square to hipster, where he gives Grump a lesson in visual thinking.
Henson did another lesson in visual thinking on Sesame Street in 1971, featuring muppets voiced Frank Oz playing the square and Northern Calloway as the hipster.
