魔理沙は大変なものをAA化していきました (Marisa turned difficult things into AA) made by John in 2007. It’s an ASCII art (AA) adaptation of the short version of Iosis’s Touhou Otomehayashi track 2, Marisa Stole Something Terrible.
It took 1-2 months to make the 600 frames of the animation, and all of them are available here.
