With HCCB (High Capacity Color Barcode) of which an implementation is Microsoft Tag you can get 1.5 MB with 600dpi color on a A4. If you add the best compression techniques (cmix v7) depending on the source material you could get 8 times as much english text, easily fitting the pearls or religion: Tenach, New Testament, Quran, Mahabarata, The Dhamapada, the Atthakavagga and the Parayanavagga, Rhinoceros and Lotus Sut…

Regarding notation for human movement, there's Siteswap ( https://en.wikipedia.org/wiki/Siteswap ) for juggling :)

Or the file manager in Fedora being called "Files".

Its real name is nautilus

Which is not present in the icon, the menu bar, the about dialog or the help file.

At least they've managed to be consistent with the rename. Compare this to Packages, which is called "packages", or "software", or "software install" or "packagekit".

And for dance there's "Dance Notation"[0], most specifically Labanotation[1], but there are others, such as Benesh notation[2].

For juggling[3] there is SiteSwap[4] for vanilla flavored juggling, and now it's been extended in different directions, perhaps most completely by BeatMap[5].

So I'd like this on medium that's a bit more permanent than paper, but with similar information density per kg, and similar re-creatability without having any of the original tools available. I'd like to store data for say 100 thousand years.

I'm not sure how long it would last but how about something like a bubblegram [1] (laser crystal)... You could use a flatter plastic block and create a 2D image inside. Also, maybe other materials can be used.

This is a revolution for transporting confidential information through customs :) If it's not electronic they won't even bother checking it!

No, sorry, it's not. That's already trivial: Take a microSD card with your info. Put it together with a couple of tablespoons of oatmeal into a tightly and well wrapped plastic package. Swallow it. Travel. Arrive. Poop. Voila. Also, if you bring big stacks of paper it will often be inspected, since a common way of smuggling currency is putting hundred-dollar bills between the pages of books.

I guess it's better to upload TrueCrypt container somewhere in the cloud and transfer just password/URL. Password/URL may be derived from the first letters of each sentence in the U.S. Constitution or other similar public source of static random data.

This reminds me of http://ronja.twibright.com/optar/

Note, Paperback has over twice the density of Optar. Not that I'm complaining. I bookmarked both because I think they're nifty, despite "media abuse" being the best tag I could think of.

Note: it's extremely easy to increase the density of optar (by editing two constants in the source). optar is configured for 200dpi by default (based on real-world testing).

Maybe I'm just slow tonight but I don't see the usefulness in the applications you're describing. >for politics or mass dissemination of paper based digital files for the public to quickly consume > Imagine, if students could start posting free textbook pdf files just by handing out a piece of paper which you could scan, or maybe with a phone one day, and instantly receive the file. With both of those, how is this mo…

You can't do anonymous mass dissemination with SD cards because of the cost. You can do it with CD-ROMs however. In China, people actually do this and sometimes you can find a CDROM with dissident political messages lying on the ground. It's also common to print anti-government messages on the money, which might be a great application of paperback/QR - higher density public messages via circulating currency.

I wouldn't trust a CDROM lying on the ground. How could you know it is not a malware ?

Why not public key cryptography?
