Animutation is a genre of surrealist Flash animation that originated in the early 2000s, primarily credited to creator Neil Cicierega with his seminal work 'Hyakugojyuuichi.' Characterized by its use of random pop culture imagery, flashing colors, and often Japanese music with misheard lyrics, it laid the groundwork for modern 'weird' internet humor. The style emphasizes sensory overload and non-sequiturs, bypassing traditional narrative for pure, unfiltered randomness. Even decades later, Animutation remains a cornerstone of internet history, representing a DIY era where bizarre creativity reigned supreme and logic was entirely optional.
