Christopher Domas gave a nice presentation[0] at DerbyCon 2012 about software that ended up becoming CantorDust[1]. I was pretty jazzed about after the presentation but didn't keep up with where it went.

You might be interested in GNU poke[1][2], a hex-editor type program that can actually parse and visualize the structure of binary data (using a DSL for describing formats).
