bidi books, bidibooks, bidimensional books

QR Code in print, [Kaywa reports]. Bidibooks, bi-dimensional (here it means 2d as in quick code) books, they're called in Madrid. But they are also bidi because they're both eye-readable, and phone-linkable to otro resources. An online appendix. Hell yes, people.



Or, as they say in Spain, "La hipertextualidad del papel es posible."
