Reminded me of this (as in, I thought I remembered something maybe named something like "optar", and googled):

http://ronja.twibright.com/optar/

which I found via this repository, that makes a comment regarding apparent abandonment of the original:

https://github.com/colindean/optar

Also from memory, there is at least one other such "ginormous barcode" utility/application that gained some attention, some years back. It may well be the "paperback" one that another commenter mentions, here.

At least one of these had configurable resolution and redundancy parameters.
