#equilateral triangles

Wobbly Sierpinski-fractal model/toy

Made with foil strips of equal length and book screws.

The larger triangle at the center is stable because the outer tinier triangles stabilize it. (The larger triangles have a side length of two foil strips. The smallest triangles ("the building blocks") have a side length of 1 foil strip. The largest triangle is this entire model with side length of 4 foil strips.)

The largest triangle (4foil strips) is stable, because the tiniest (1foil strip) triangles stabilize each other as well as the larger (2foil strips) triangle.

The sierpinski pattern has interesting properties regarding its "stability" I have to admit.

Normally I struggle to make equilateral triangles of side length "2 foil strips" stable enough without adding an inner triangle. This construction (using outer tiny triangles) is a good solution if you want a "larger triangle hole".

I know a lot of people like the equilateral triangles because of Bill Cipher but you do have to understand that they are, as a class, helping to oppress the lower classes. That's what the middle class does. That's literally the Entire Point of having a middle class. Just because they're not higher ranking doesn't mean they're not helping to oppress the people below them. No, they're not considered Gentlemen or Nobles...but they also are not literally chained in place and starved to death in schools for children of nobles either.

Put down the Gravity Falls-tinted glasses and actually look at the actual Flatland society presented to us. Just because you like Bill Cipher and he's an equillateral triangle doesn't mean you shouldn't be understanding the role that the middle class plays in oppressing the lower classses, both in Flatland, and in real life.

In Flatland, equillateral triangles absolutely hold power over the lower classes, and actively help to oppress them. If you don't understand this then you are failing to understand many of the themes of Flatland, and basic facts of how real society functions as well.

You liking Bill Cipher doesn't mean you get to pretend that the Middle Class isn't literally essential for continuing the oppression of the lower classes both in Flatland and in reality. Thinking so will only further ingrain real classism into your brain and politics.

Eat the rich includes your favorite characters. Yes, even characters who are only in the setting as a crossover. If you can't recognize systems of oppression in satirized fiction created to draw your attention to them, then you have no hope of combating them IRL, even just inside your own head.

A 10" d4 I made for Therin (& Lemon).

This is my own , new design. So many things I would do differently next time. But its really cute. I like it and they will, too.

stupid hipsters

get it together people. they put triangles on their bullshit and they're not even equilateral triangles; they're fucking isosceles. if you're going to try to be cool, at least do it right. fucking posers.
