->''[[CatchPhrase "Let's say you're me and you're in math class..."]]''

Vi Hart is a "recreational mathemusician" with [[http://vihart.com a site]] and [[http://youtube.com/vihart a Youtube channel]]. She really gained her fame when Creator/{{John|Green}} [[WebVideo/VlogBrothers Green]] [[http://youtu.be/gep4QH6U27M?t=2m21s discovered her]] as part of The Station Is Watching You, and has since gotten herself over 180,000 subscribers on Youtube. As you could guess from her "job title," her videos center around math and a little music, as well as doodling.

----
!! Vi Hart provides examples of:

* BrickJoke: Every single of her "Doodling in Math Class" videos, where she notes what the math teacher is talking about, and later comes at the exact same topic with her doodling.
* CallBack: In The Gauss Chrismath Special.
--->"Maybe he also liked to [[http://www.youtube.com/watch?v=CfJzrmS9UfY escape via the window]]..."
** [[http://www.youtube.com/watch?v=Gx5D09s5X6U Snake snake]] [[http://www.youtube.com/watch?v=ktW43nEqcDg snake snake.]]
*** [[http://www.youtube.com/watch?v=xbsAUq_nvxE Snail snail snail snail.]]
* CatchPhrase: As previously mentioned, "Let's say/Pretend you're me and you're in math class..."
** [[SubvertedTrope Subversion]]:
--->"...Actually, never mind, I'm sick, so I'm staying home today; [[http://www.youtube.com/watch?v=Yhlv5Aeuo_k please pretend you're Stanislaw Ulam instead.]]"
* ChekhovsGun: Zig-zagged in the Sick Number Games video. At the beginning, Vi has her infamous white paper, but when she says "[[AndNowForSomeoneCompletelyDifferent pretend you're Stanislaw Ulam]]", she gets rid of her white paper, and replaces it with yellow paper. Said yellow paper is used by Vi for most of the video, but then she says "you could also be Blaise Pascal", and the white paper comes back, with it being used for pretty much the rest of the video.
* ChristmasSpecial: [[http://www.youtube.com/watch?v=sxnX5_LbBDU The Gauss Christmath Special]]
* CoolTeacher: Fans want her to be theirs. And since she's one of the minds behind Khan Academy, she sort of can be.
* FoodPorn: Her Thanksgiving mathematical food videos, with the capper being a Turduckenailail-enailail-duckenailail-enailail, a turkey stuffed with two ducks, each stuffed with two hens, each stuffed with two quail eggs. Also her "hex mex" hexaflexagon burrito.
* [[spoiler: HoldingBothSidesOfTheConversation: [[http://www.youtube.com/watch?v=4mdEsouIXGM Wind and Mr. Ug]] are actually the same guy, except mirrored, due to the way a Möbius strip works. As such, Wind is writing to herself, but, reading mirrored versions of her words and buildings, she believes a different guy is there with her.]]
* MotorMouth: Without any doubt, she has one.
* MundaneMadeAwesome: [[spoiler:The number 1]] is turned into Wau, of which many unusual properties are listed.
* NerdsAreSexy: Comments on her videos and channel have included such gems as "she sounds hot and nerdy," "are you single," "i want to make babies with you," and "my brain has an erection."
* PurelyAestheticGender: She sees gender in real life as this, and refuses to accept any gender identity (even agender).
* RunningGag: Many of her videos have some form of this, including Beans for [[http://www.youtube.com/watch?v=X1E7I7_r3Cw "What was up with Pythagoras?"]] and VideoGame/AngryBirds in [[http://www.youtube.com/watch?v=v-pyuaThp-c Connecting Dots]].
* SecondPersonNarration
* SelfInsert: Arguably, Wind from [[http://www.youtube.com/watch?v=4mdEsouIXGM Wind and Mr. Ug]], seeing as Vi depicts both herself and Wind as triangles, while other people are stretched-out stickmen.
* ShoutOut: She's done plenty.
** You can see [[Literature/TheLittlePrince a boa constrictor digesting an elephant]] in [[http://www.youtube.com/watch?v=heKK95DAKms Snakes + Graphs]].
-->"[[http://www.youtube.com/watch?v=ktW43nEqcDg What's that thing]] [[Franchise/TheHitchHikersGuideToTheGalaxy suddenly coming toward me very fast?]]"
** Later in the same video, on a silly band:
--->"It's actually [[Franchise/TheHitchHikersGuideToTheGalaxy the splash a dolphin makes as it leaves this world because it's about to be destroyed by aliens.]] Or maybe it's just inside out? It's '''obviously''' [[CthulhuMythos Cthulhu]]. Or upside down. I guess it's a [[Franchise/HarryPotter hippogriff]]?"
** A lot of her shout outs are things she's drawn in the background of her main doodles: [[Literature/HarryPotterAndTheDeathlyHallows the deathly hallows]], [[{{Videogame/Portal}} the Aperture Science logo]], among others.
** In Doodling in Math Class: Snakes & Graphs, one of the snakes in her mini-rant regarding language is speaking [[Literature/HarryPotterAndTheChamberOfSecrets parsletongue.]]
** In Doodling in Math Class: DRAGONS, she decides that one of the dragons she created is a [[Literature/HarryPotterAndTheGobletOfFire Hungarian Hornail.]]
* TheFaceless: Most of the time in her videos, she only appears as a pair of hands. Unlike WebVideo/CGPGrey, though, she is not maintaining a secret identity, instead wanting to show her notebook in detail, and will gladly appear uncovered in other people's videos.
