so I asked CharGPT 4o „why would 27 be the preferred pick for a number between 1-50“ and the answer is quite interesting and multifaceted:

Great question. While 27 isn’t inherently superior to other numbers, it is often a preferred or psychologically “sticky” pick for several cognitive, mathematical, and symbolic reasons. Here’s why someone might subconsciously or deliberately choose 27 from a range between 1 and 50:

⸻

🧠 1. It’s Odd, But Not Too Odd
•Humans often prefer odd numbers — they feel more “random” and less round or predictable than even numbers.
•27 isn’t too low (which might seem too obvious or simplistic), nor too high (which might feel extreme), making it a comfortably unassuming middle pick.

⸻

🔢 2. Mathematically Appealing
•As the cube of 3 (3³), it’s one of the few perfect cubes under 50, which gives it a pleasing structural identity.
•It’s also divisible by 3 and 9, both of which are considered “lucky” or powerful numbers in various cultures.

⸻

🌀 3. Strong Numerological Symbolism
•In numerology, 27 is often reduced to 2 + 7 = 9, a number associated with completion, wisdom, and humanitarianism.
•9 itself is seen as a “magic number” — every multiple of 9 returns to 9 when its digits are summed (27 → 2+7 = 9).

⸻

🎸 4. Culturally Iconic
•The “27 Club” of iconic musicians who died at age 27 gives it a kind of mysterious or legendary aura.
•Appears in pop culture (e.g., 27 Dresses, 27 Club, and references in music and film).

⸻

🎯 5. Cognitively Sticky
•Research in cognitive science shows people often prefer numbers in the 20s over other ranges when asked to “pick a random number” under 50.
•27 specifically comes up more than others in informal studies and polls — it’s often seen as random enough, but not meaningless.

So while 27 isn’t objectively “better,” it carries enough mathematical and cultural significance — while still feeling random — that it often feels like the right choice.

Shopify just launched a racing game built in threejs and React (R3F).

No physics libraries. No raycasts.

Not vibe coded. But all vibes. ✨

This would be a good time to mention that one of this year's Apple Design Award winners is a WebView app using React and @threejs. I think we are safe.

Stunning work by the folks at @feather_3d btw, absolutely worth the 15 bucks. One of my favorite creative apps of all time.

Programmers prioritize the feeling of productivity over productivity itself. They prefer to rewrite a codebase with tools they are comfortable with (thus, feelings) even if ROI is years away, instead of e.g. fixing a bug (actual productivity).
