http://tvtropes.org/pmwiki/pmwiki.php/Music/BadApple
“Bad Apple!!” is a chiptune stage theme from the game series Touhou Project that received a popular remix (under the same name) from the Touhou Fan Music group Alstroemeria Records. Said song later received a fan-made black-and-white music video that exploded in popularity on the internet, becoming a viral video in the late 2000s.
The original “Bad Apple!!
In August 2008, on the Japanese video website Nico Nico Douga, the user Μμnote Mu-mu; mu as in the Greek letter released a video of a crude storyboard for a music video to (a slightly shortened version of) Alstroemeria’s remixed song. The storyboard consisted of a series of clips, each displaying a Touhou characternote Specifically, from the modern Windows era Touhou games, from Touhou Koumakyou ~ the Embodiment of Scarlet Devil to Touhou Fuujinroku ~ Mountain of Faith, and requested other users of NND to animate the MV. Several users attempted to produce an MV based on this storyboard, but one stood out among the rest.
On 26 October 2009, a collaborative group led by user Anira (あにら) released a black-and-white animation
While technically just a fan video, the popularity of Anira’s video attracted the attention of Alstroemeria Records, who unofficially adopted the video as the song’s official MV.
In the mid-2010s, Anira’s music video saw a resurgence as an internet meme, where the video would be played/replicated on all sorts of normal and wacky mediums like graphing calculators or Minecraft sheep. Thanks to the stylized, silhouette-based art style, any medium capable of producing two contrasting colors can theoretically be engineered to play “Bad Apple!!” on it, making it the video equivalent of wacky Doom ports.
