Mosaic
A 29mm sapphire disk, etched in gold by semiconductor lithography. 1,124 tiles. One physical run.
… of 1,124 tiles filled. … remain.
File locks on May 24, 2026. After that the disk goes to fabrication and the contents are permanent.

Upload is free. You send a 500×500 monochrome image — anything you can express in pixels. Your image joins the collective disk; every contributor's image appears on every disk.
To request an upload link, send us an email. In the body, briefly mention what you plan to upload. This is mostly for spam control, but we're also excited to hear your ideas.
If you want the physical object afterwards, it's $150 — but uploading doesn't require buying. Everyone who buys gets the same finished object with their own image and everyone else's images on it.
What's actually happening
South Slope Nano Devices is fabricating one run of a 29mm sapphire disk. Each tile is a 500×500 monochrome bitmap. The bitmaps are etched in gold using the same semiconductor lithography used to make microchips. The result is too small to read with the naked eye — you can see something is etched on the disk, but the individual tiles need a microscope.
The full-resolution contents always live publicly at mosaic.southslopenano.com. That's the canonical way to read what's on the disk. The physical object is the souvenir.
Honest notes
- The disk is too small to read with the naked eye. Get a microscope, or use the public viewer.
- Every contributor receives an identical disk — every image, on the same coin.
- The public viewer at mosaic.southslopenano.com is permanent. Don't upload anything you wouldn't be comfortable being seen forever. We also expect the physical disks to be around for the next 10,000 years.
- Be cool and creative. We review every upload before fabrication. Anything we wouldn't want next to our own image gets bounced.
- Hard cap of 1,124 tiles. When May 24 hits, the file locks. Then never again from this team.
