I can't remember where I got this, but very quick....

Hold both hands in front of you. Fingers up, thumbs tucked into your palm.
Have your palms facing towards you. Each finger represents a bit. Extend a
finger upward for each '1' and fold it down for each '0'.

You now have represented the byte with your hands.

To convert, rotate your palms away from you and then cross your forearms to
make an 'X'. Read your fingers to reconstruct the HEX representation. Works
going from canonical to non-canonical and vice versa.
