I'd actually pay money for it...
There's not a whole lot to work with, admittedly. The MPH gauge has two seven-segment-equivalent displays (though you can do a couple creative things, like that exclamation point), and a single 1 in front of them. The 1 is either all on or all off.
The trip meter area has 9 total seven-segment digits plus a leading 1 on the far left side (for 100.0+ mpg).
I think the instantaneous fuel numbers are actually (almost) all seven-segments too... you might be able to display custom numbers on those tiny digits. I know that the "0" marker is all on or all off, no segment control there - but the others seem to be full seven-segment digits. I'm not entirely sure, I haven't mapped out the whole display yet.
Of course there's also the bar graphs for RPM, temp, gas, assist/regen, and SOC.
The rest of the stuff on the display is just the specialty icons, like "mp/h", "km/h", "trip a", the trip segment arrow, etc.
I think there's a lot of fun things you could do. I'd like to change the assist and regen bars to show absolute amps or watts in/out of the pack, no matter what gear you're in. And SOC would show the real SOC, of course. We could even make the temperature gauge actually useful with a different range or scale (like samwichse said). I've also always wanted the fuel gauge to be linear. A pretty small thing, but it would make me happier.
You could possibly do something creative with the normally-unused portion of the RPM gauge - everything past the redline is never seen in normal driving. You could use those to indicate something if you wanted.
Even silly stuff like swap the MPH and RPM gauges - not sure why you'd want to, but you could in theory! Or make custom startup animations.
I'd imagine any OBDII parameters would go in the MPG seven-segment display area. Unfortunately, you can't do certain letters with seven-segment displays, but we can work around those.
The real question is how you set up what you want. I'll need to add some external controls somewhere.

And the temperate gauge show a compressed scale say... 1 bar=2C with 92 in the middle.
I was actually thinking the exact same thing with the auto-stop light!
If anybody else has ideas or feature requests, feel free to throw them out here.
And Balto - could you find a slightly smaller image? It's stretching the page even on my 2560x1600 monitor!
