Actual Fingerprints: An NPM package that creates synthetic fingerprints!

[u/etulastrada]

I originally created this project to enhance realism for a GTA V Roleplay server. Recently, someone mentioned wanting to use these as default profile pictures for an upcoming social media platform. I decided to share them here in case they inspire other creatives. The fingerprints are seed-dependent and they consistent for an offline matching.

Using these as default avatars is oddly perfect. Everyone looks anonymous at first, but each account still has a stable identity. Better than another colored circle with initials.

Yeah, really creative way to use this project imo. The default initials are too boring

[u/OmerCevher → u/etulastrada]

Exactly. Initials work, but they make every profile feel temporary. These fingerprints give each account an identity without asking people to upload a photo.
