#OCTAHEDRON

octavian theatrical motif ‼️

You can insert an icosahedron inside an octahedron.

If the edge length of the octahedron ist 1 + Phi (1.618), the egde length of the icosahedron is SQRT(2).

A friend showed me this picture by Casey house:

And I had to draw it in isometric projection.

Very neat.

One could also make that even further and put an octahedron into the icosahedron and so on...

Okay I'm back with another silly obscure character for you!

Maybe OCTAHEDRON Protagonist?

hang on i recognize you from here

but who am i to deny you your polygonal drug of choice

for future reference though you need to not consume so many polygons because polygon addiction can have serious consequences

dont do drugs children

Whatever this thing is, the way your eyes are straining when you try to focus on it are saying that the way you're currently perceiving it is protecting your mind from sensing something far, far beyond human understanding. Its dragon-esque body consists of what looks like hundreds of thousands of individual shapes that each have their own color. No two shapes have the same color. Where its head should be is a floating octahedron that is so bright you can't look directly at it. It's like staring into the sun.

Its breath weapon is a flurry of countless individual paper-thin shapes launched at incredible speeds. Each shape individually only leaves behind a paper cut, so you can imagine how deadly all those shapes being launched at you at once is.

Please reblog for a larger sample size.

Sometimes I remember that most of the games I love are extremely obscure and at most have five other people in the fandom.

Anyways, do anyone else knows about 140, THOTH, HoB, OCTAHEDRON: Transfixed Edition, THUMPER, VVVVVV, Billie Bust Up, NERVE (Gunfish Games), TY the Tasmanian Tiger, Owlboy and/or JUMPGRID?

[concoctionboy]

One neat thing about being a shapechanger is that if someday I happen to think "Hm, I wonder what it is like to be an octahedron?", I can just turn myself into an octahedron and find out.

(It turns out that being an octahedron isn't really all that interesting. But I wouldn't have known that if I hadn't tried.)

Don't forget that there's a game called OCTAHEDRON!! With an equally banger soundtrack!! Also the protagonist is octahedron-headed btw. They're a silly little (tm) guy.

Regular Icosahedron:

Platonic Solid

A visual study of the Icosahedron inside an Octahedron - and the remaining tetrahedral modules

The tetrahedral modules:

Buckminster Fuller came up with these modules and called them "S modules" or "S quanta modules".

Here is a helpful summary:

[art-of-mathematics]

4 tiny tetrahedra friends (red, blue, yellow, green) and 1 octahedron guy (violet) make up the big tetrahedron squad (packed densely into a pretty nice tetrahedron glass cage):

(The octahedron guy is at the center of the friend group. Does it make them the mom friend?)

Release them from their glass cage and enjoy their company in the wild:

Here are the 5 members of the big tetrahedron squad, aligned into a fine line.

Here they begin stacking each other again:

The green friend gets lifted into the air:

The yellow friend is in the cage again:

after years of not doing it, I’ve finally made a gemsona :3

idk if those pictures are different kinds of pyrite, but they’re all definitely pyrite. some are just iridescent like that.

though it’s definitely not my color, i LOVE pyrite for being able to form platonic solids. cubes are most common but these guys are a couple of octahedrons. they’re a lil special i love them.

silly guys bubby and coomer from hlvrai. please watch it. the pyrites are probably some sort of scientists i guess because these two have been living in my brain

bonus: my irl pyrite shaped into a stella octangula i love it i love it

Yatevon transcript

Yatevon Octahedron A single-minded univore from the land of Dodecas, with a curious hunger for floating platforms. Octahedron - 004 - (005) Limited Edition

Propaganda and spoilers under cut

Yatevon: It's only purpose is to be an annoying enemy that steals your platforms. It's described as a "simple minded univore with a curious hunger for floating platforms". Oh and it's named after Yateveos.

Echo Flower: The Echo Flower is a mysterious cyan flower that repeats back whatever words it heard last, over and over. In Undertale, you can use it to hear conversations of passersby.

Amputechture (2006), The Bedlam in Goliath (2008), Octahedron (2009), Noctourniquet (2012), The Mars Volta

While I may have expressed a certain fondness for early Mars Volta records, that sympathy doesn’t extend to the rest of the band’s catalogue. At one point, Omar Rodriguez-Lopez and Cedric Bixler-Zavala entirely lost me; not just unenjoyable but lengthily so, Mars Volta records lost all impact. These releases can only justify themselves with exceptional amounts of lore and extended reading – all of which perhaps indicates that the music itself says very little. 

Pick(s): ‘Vermicide’, ‘Metatron’, ‘Since We’ve Been Wrong’, ‘In Absentia’’
