It isn’t unusual to find well known works of art in anime. Below are two of the more recent ones I found.
The first picture, from Kanon, is a cropped version of The Birth of Venus by Botticelli. Of course, everyone should know this; if you don’t, you need to get out more. The second picture, from Happy Lesson The Final, is relatively more difficult to identify, but it’s obviously Arearea by Gauguin; it’s just flipped horizontally. Gauguin is a bit more obscure, but any beginner art student should be able to recognize it.
Well, enough of the foray into the art world, go take a look at the more mundane tide breaker I found recently.
