That is a huge problem. A better solution would have been an app which takes a url and shows a sketch of triangles or squares which the user can then write out. Such an app could work offline as well.

How many shapes would you need to draw to encode even basic data like an 64 bit string of text?

Serious question...would it be something that a person could sketch out quickly by hand? Or end up being a massive diagram?

I've been reading the book "Code" where they start getting into the combinatorics side of things, but still relatively new to it.
