Here’s a trix, or triangle divided into six smaller triangles:

Trix, or triangle divided into six smaller triangles

Now each sub-triangle becomes a trix in its turn:

Trix stage #2

---

And again:

Trix #3

---

Trix #4

---

Trix #5

---

Now try dividing the trix and discarding sub-triangles, then repeating the process. A fractal appears:

Trix fractal #1

---

Trix fractal #2

---

Trix fractal #3

---

Trix fractal #4

---

Trix fractal #5

---

Trix fractal #6

---

Trix fractal #7

---

---

But what happens if you delay the discarding, first dividing the trix completely into sub-triangles, then dividing completely again? You get a more attractive and symmetrical fractal, like this:

Trix fractal (delayed discard)

---

And it’s easy to convert the triangle into a circle, creating a fractal like this:

Delayed-discard trix fractal converted into circle

Now a trix fractal that looks like a hawk-god:

Trix hawk-god #1

---

Trix hawk-god #2

---

Trix hawk-god #3

---

Trix hawk-god #4

---

Trix hawk-god #5

---

Trix hawk-god #6

---

Trix hawk-god #7

---

Trix hawk-god (animated)

---

Trix hawk-god converted to circle

---

Trix hawk-god to circle (animated)

---

If you delay the discard, you get this:

Trix hawk-god circle (delayed discard)

---

And here are more delayed-discard trix fractals:

Post-Performative Post-Scriptum

In Latin, circus means “ring, circle” — the English word “circle” is actually from the Latin diminutive circulus, meaning “little circle”.
