I always found it useful to have a chart of all of the boolean operators (and the symbolic logic operators) in one row. This shows all the possibilities at a glance, and also shows how there are "special" operators which can be used to construct all the rest. (NAND and NOR particularly). Another interesting thing to do is to create a binary tree with 4 levels and then mark off each leaf as representing a given operator (or identity), which reveals that there are several potentially useful binary operators which are almost never used.
Anyway, just thought id mention this as it seemed somewhat germane. :-)
<Elian> And I do take a kind of perverse pleasure in having an OO assembly language...
