Like very high resolution version of this image. Where each paper (note) could have different “types” on it e.g. bitcoin, football, art, cars, science etc etc

Users may have different skin colors, national clothes, flags. Clients could indicate android, ios, web. Relays may indicate different programming languages. Different sides of image could be day/night/winter/summer. Clients may also indicate photos/texts/audio specialization etc etc to show ubiquitous design of nostr — I would zap this a lot
