Hogan's 'plane of glass' Plane illustration is arguably the most famous illustration in golf. It is also among the most erroneous. Especially when combined with the three accompanying illustrations showing the 'baseline' shift to the right during the Downstroke.
My benchmark of "important" demands that the illustration also be correct.
I think the one you put up there is hard to beat Yoda,
But if you develop it into something like this, it will be even better, IMO:
A Bobby Jones like strobe with visble hands and without the flip through impact will tell still tel a lot about the ideal impact position but also a lot about H2 get there.
I couldn't figure out how to grab and post that, Bernt!

Thank goodness I'm not a computer teacher!

Great, BerntR. Who else has an entry? This is fun!
Your swing had better be as good as your software!

Next?
If the benchmark is that the illustration also be correct wouldn't that disqualify your pic. also as it doesn't include a real event of impact as no clubshaft will be in that position in a real swing at impact. They actually deflect the exact opposite way at that moment as the clubhead goes to a lead position from a lag position.
sasho mackenzie says:
"The final phase of shaft deflection was the most
important since it explained clubhead orientation at impact.
Over the final few hundredths of a second of the downswing,
the clubhead rapidly moved from its maximum
lagging position into its maximum leading position at
impact. The lead deflections at impact for the normal
optimized simulation were approximately 6.25 cm in
magnitude. The complete removal of radial force during
the downswing only reduced lead deflection to 4.72 cm
(Fig. 8; Table 1). Therefore, when acting in isolation, the
tangential forces that occur during the late phase (after
0.15 s) of the downswing were a major contributor to the
lead deflection at impact. The complete isolation of radial
force demonstrated that, while acting alone, radial force
only resulted in 1.22 cm of lead deflection at impact
(Fig. 9; Table 1)."
