Inspired by the Binary Visualiser explained and demo'ed at the other end of that link I messed around making a quick version myself:
In the above image blue denotes text byte values, green any other positive byte values and black zero. I will leave what the file could be up to your imagination :P (not that the whole file's data is visualised here, only about half) This particular file exhibits some interesting striping and the last quarter of the file is mainly text.
I doubt this will be of much interest to people who aren't as fascinated by data visualisation as I am. Ideally I would find a way to divide a binary executable into likely; logic, audio, graphical and text data. This topic would probably descend into disassembly though, which is sadly a bit of a legal grey area :/ A pity as it is wonderful to see computer code at the level of bits and bytes.
