senseye seems to match the featureset from cantor dust pretty well but other than 'pretty pictures' its hard to see how its useful

The "intuitive" feeling that he claims to develop after using it for awhile seems like it would be useful of you do a lot of reverse engineering or forensics work.

yeah perhaps I just havn't gotten the feel for it - think I've spent some 8-10 hours total playing around (more comfortable with regular hex+disasm+debug+scripts), I liked the https://github.com/letoram/senseye/wiki/Sense_MFile thing though

This looks pretty cool. cantor.dust seemed more usable than senseye (I haven't used either).
