Rob,
 
Your panel is a Coke Classic.   Uh, mine is pretty much classic.  This is 30 minutes into a best power flight at 5500 MSL, 25 squared, 182 KIAS, timing of 24.5 DBTDC and 10.4 GPH.  I am sure you can find other data.
 
Center:The Monroy traffic alerter is just below card compass.  The Garmin 430W replaced a Garmin 155 and Terra Nav/Com pair.  The silvery face plate is for the ADF (Audio Data Fortifier) - a replacement for the original Terra ADF and a place I can plug in monaural inputs or power the XM radio.  I just kept the letters the same so I didn't have to change the breaker ID.
 
OK,  lower down is the usual.  Throttle, prop, mixture and an extra PTT next to the throttle.  Blue switches that control the automatic header-kept-full function and wing fuel pumps and then various data/power outputs.  On the console is lateral trim, a speaker, Reichel elevator trim wheel (walnut), rudder trim and the hydraulic system breaker. 
 
 
On the left - a lateral trim indicator, vac gauge, timer, gear sw, idiot lights, gear status, pump status and squat override.
The usual instruments, AOA on the left near where I look out the window on landing, RMI air data, S-Tec 50 w/GPSS, etc.
 
 
On the right are more less important idiot lights, engine monitor and some light switches.  Oh yeah, circuit breakers.  THe black thing occupying the ADF indicator hole are the LSE ignition display.  To the right is the alternate EI power source switch and the Essential bus switch.
 
 
I think your air eyeball hoses are way too big.

 Stan -
 
 Your control panel looks beautiful!  I have just a few comments on minor
details:
 
 1)  The picture of the airplane above the wheel lights looks like it is
pointed at you, therefore the landing gear light on the right side of the
picture looks like the landing gear under the left wing.  I think it would be
better if the left light in the cockpit represented the left wheel.  Maybe
your picture should be of the *back* end of the airplane, or a top view.
 
 2)  Studies have shown that a long row of similar switches makes it more
difficult to identify the proper switch.  One must absolutely read the labels
rather than, say, activating the second switch in from the end.  Regardless,
the message is that long rows of identical switches is correlated with
flipping the wrong switch.  These studies recommend having no more than 5
identical switches in a row.  Perhaps you could introduce a gap so that your
ten white switches on the lower left are in two groups of five.
 
 3)  FAR Part 23 recommends having the flap handle and the gear handle located
as far as possible from each other.  Yours are one on top of the other.  Sure,
they are shaped differently, and I'm sure you have a "lift lock" gear switch
(must pull it out a little to raise or lower it) but you might consider moving
the gear switch to the other side of the left glass panel -- it looks like
there is room.  Besides, the front center of the panel is prime real estate,
and since you only actuate the gear switch twice per flight, you can probably
afford to put it over on the left edge.
 
 One thing I like is your use of engraved switches to minimize the number of
placards.  I have done the same.  You can get engraved master switches as
well.  As far as radio locations, my preference is for the audio panel to be
at the top of the stack, but that's only because it is what I'm used to.
 
 The panel is probably the place where we are most free to express our
individuality.  It's fun to see what each person comes up with.  Mine is
probably too "retro" for the 21st century, but it represents the era in which
I stared building.  All steam gauges and wood grain, with engraved brass
placards.  If I started it today I'd probably go for the glass.  I don't do
much IFR -- I punch through the California marine layer but not much else --
so the improved situational awareness of highway-in-the-sky, synthetic vision,
and the other cool modern stuff won't be missed.
