It's the first day of 12th grade and Magini has his shiny new notebook out!

It's not, admittedly, the notebook he was planning on taking notes for 20th Century World History in (he'd wanted to use this one for HL IB Bio), but he apparently put the wrong one in his backpack and it's too late to go back to his locker now.

Mrs. Sutherland hasn't started saying anything interesting yet (she's busy giving a version of the same excited preamble she gave in 10th grade, which is charming, but not attention-holding), so he absent-mindedly doodles a twisty impossible tribar using the very specific method he came up with for it. (Magini has many talents; freeform art is not one of them).

 

 

Magini's 7-step process for drawing Twisty Impossible Tribars

1. Draw an equilateral triangle; near the midpoint of each side, sharply curve it outward on both sides towards a point.



2. Give it feet by extending each side outward in 1 direction.



3. From each midpoint, curve a line outwards in the direction of the nearest foot such that it becomes parallel with the inner side well before it connects to the foot.



4. Draw an outline of the entire shape, about about 1 foot-length out.



5. From each outer corner, add another foot that runs parallel to the opposite side of the triangle.



6. Complete the tribar by extending a line from each outer foot that runs parallel to the nearest edge before curving into it at the midpoint of where that edge starts to curve outwards.



7. Shade the outer and inner isolated regions.

He inspects the results with a critical eye. It's... satisfactory, though definitely not his best work. (Magini gets better at drawing his little shapes as the school year goes onwards, and then gets much worse over summer vacation because he isn't doodling as a classroom-acceptable stim.)
