  The working mathematician fears complicated words but loves pictures and
diagrams. We thus give a no-fancy-anything picture rich glimpse into Khovanov's
novel construction of `the categorification of the Jones polynomial'. For the
same low cost we also provide some computations, including one that shows that
Khovanov's invariant is strictly stronger than the Jones polynomial and
including a table of the values of Khovanov's invariant for all prime knots
with up to 11 crossings.
