dd + hexdump + more is available, but that combination is a little bit too basic. 
Desired features :
1. Random access ( ability to jump straight to any offset )
2. Scrollability ( ncurses or gui )
3. Filesystem agnostic
4. Displays Offset, Hex, ASCII ---> e.g. 0000: 4A 46 49 46 00 16 01 48 JFIF...H
5. Displays partitions and their offsets.
I run Openbox on Debian.
Thanks.
