Streetwear 2.0
A zodiac hoodie that turns a scan into a real encounter.
Inspiration:
I am an artist, and I work as a printer. After 11 years as an art director and graphic designer, I know how an image lives on fabric. I imagined Astro Code as a reason to go out: a garment that starts face-to-face encounters. You can have a million followers and still end up eating alone. With Astro Code, you don't "follow" people. You meet them.

What it does:
A phygital streetwear concept: a hoodie with a zodiac sign on the chest. Point your phone at the design: a creature comes alive in AR around the wearer. A sign only enters your collection when you have physically met the person wearing it.
Meet: a radar shows nearby wearers open to being approached (the Wave). Scan: the creature comes alive with a personalised horoscope; two signs meeting triggers a spoken icebreaker. Keep: one tap creates an illustrated memory of the moment.
Also built in: Duo Fusion (two signs together merge into a third creature); today's horoscope, fresh every morning; Try a Hoodie Live (voice try-on, no hoodie needed); Astro Garden, a farm run by voice commands (Muse Voice Transcribe); The Imprint (all 12 signs unlock your own words on your garment).
Consent first: the Wave is strictly opt-in — nobody appears available unless they switched it on. Written into the code, not just the terms.

Try it (3 minutes, Android): open astro-code-5.netlify.app, tap SCAN, aim at the README photos (github.com/Nezzart05/astro-code), full screen or printed. Pisces: the show + today's horoscope. Leo: the encounter + icebreaker. Both in one frame: the Duo Fusion. During any scan, tap KEEP A MEMORY.

How we built it: plain JavaScript in the browser — no framework, no install. MindAR tracks the designs; a custom 2D canvas engine draws the show. Five Meta models power the features — detailed in "Use of Meta AI products" below. A hoodie links with a phone number, nickname and scratch-off code (on-device for now).

Challenges: our target file held a third target (the two-wearer photo) that contained the whole Pisces drawing — a long Pisces scan could trigger the Fusion alone. Removed, recompiled clean: Fusion now needs both signs at once. On iPhone the scan background renders black — full experience on Android Chrome today.

Proud of: two signs (Pisces, Leo) work end to end through every system: scan, voice, horoscopes, icebreaker, memories, fusion, Wave, collection, garden, moderation. A sign is real data, not a cosmetic option: the twelfth takes artwork, not code.

What we learned: every model has its own speed — SAM's seconds suit a try-on key frame, not a live stream, so MediaPipe cuts the wearer out live. A passed test is not a product: everything was finished twice — in code, then in someone's hand.

What's next: physical hoodies with NFC chips; the multi-user backend; the ten remaining signs; the iPhone fix; the app in smart glasses.
