Standard “they don’t know” meme format, featuring line art of “That Feel Guy” wearing a party hat standing in a corner while other people are dancing. An image of an icosahedron formed by three mutually perpendicular golden ratio rectangles sits in front of That Feel Guy. The caption text says “They don’t know that three mutually perpendicular golden ratio rectangles, with edges connecting their corners, form a regular icosahedron.”

    I love to be pedantic so I’ll point out that it had to be 3 equal mutually perpendicular golden ratio rectangles

    I knew this!

    On the off chance that one of you needs to model an Icosahedron / D20 in CAD, constructing three golden rectangles is often the easiest way to go, as it removes the need for calculating face angles.
