Questions to think about

Which part of the collection should be hidden? Why?
Based on which metadata variables are the shapes created?
Which feature would transform the 3D generated shapes into 3D printable files?
Who:

Who is using it? Only PZ?

What:

Most important features?

Where:

local? networked? physical space?

When:

temporary? always available?

Why:

what is the goal?

How to make it interesting and expandable?

Project proposal

3D steganography version of the library
3D shapes printed with the 3D printer from the school
circumvention of censorship
simhash process + MD5 Hash - showing the visability in the 3D shape (shows the evolution of the collection)
with a 3D scanner it will be possible to access the collection of the library again
mirroring and visualising the collection
alternative way of looking at the collection
compression
time capture in 3D file

What would be an alternative way of looking at the collection?

An additional feature of the X-Lib is the 3D steganography library based on WebGL. Parts of the collection such as links or PDF's are transformed based on the metadata into 3D shapes. Through a stenography script the source link (simhash or MD5 hash) will be decrypted inside of the 3D shape. During the transformation phase the platform generates an encryption code as well. The 3D generated shape will be possible to 3D print as well. With help of a 3D scanner the 3D shape could be scanned and with the encryption code the original content would be revealed. This project explores new possibilities of mirroring and visualising digital libraries in physical manner.
