Here's a good example of bad bokeh. I can say that 'cause it's my photo.

CPC 28mm f/2.8 with six-bladed diaphragm. Macro-focusing, good resolution
and little distortion - but *ugly* bokeh. The caption explains it, but to
sum up it's the best/worst example of cross-eyed bokeh I've seen.
Here are some others with various lenses:

Of the 35-105/3.5~4.5, 50/1.2, 135/2.8, 200/4 and 300/4.5 Zuiko's, I
consider the 135/2.8 the best with bokeh behind the DOF. Wish I had a scan
of one done with the 85/2 because it's excellent also. The 35-105/3.5~4.5
image doesn't show it dramatically, but it's bokeh is pretty good also. The
second image for the 300/4.5 shows bokeh in front of the DOF (focus was at
infinity). The 50/1.2 does well until you get very bright, distinct,
pinpoint specular highlights when it picks up the aperture shape (the
octagons are how I know it was this lens). The 40/2.8 Sonnar and 50/1.5
Sonnar both have beautiful bokeh, especially the latter with 13 aperture
blades that have curved edges, although it doesn't show of as well in
these, which are the only scans I have showing DOF control.
Here's proof you _can_ get DOF control out of _any_ lens, except perhaps
the 8/2.8 Fisheye. Did this one for the bokeh TOPE with the 18/3.5 Zuiko
rectilinear stacked on a 7mm Auto Extension Tube. Not great composition;
did it as an experiment just to see what it would look like. Not the best
bokeh either, but not too bad. In fairness to Olympus, I don't think
designing this lens for smooth bokeh was uppermost in their minds:
