another idea

it is about a way to read an forbidden book or information. and it is a useless way.

smell sculpture,

found an  forbidden book for X country, and powdering the book ,  and mix gunpowder and other material to make it as an huge hanging incense which normally be seen in temple. and sell it  to readers who from the country forbid this book.

and people can stand inside the incense, smell the book.
