The pic in 'Spark Discharges' by Bazalyan does not appear to resemble
an exploding wire, as it meanders quite a bit, almost doubling back 
on itself at some points.  In the exploding wire shots I've done
(up to 50 ft range) the discharge closely follows the trajectory of
the wire (usually a straight line).
