I've mostly finished the work on a new symbol set. I'll release it first
on aprs.fi (pretty soon), and then open-source the data. The new ones look
pretty good on modern displays, even when rotated as bitmaps:

That effort, however, only targeted the old symbol set, and none of the
new ones, mostly because drawing a lot of additional symbols takes a lot
of additional time, and it took a lot of time to just do the old ones
(some 30-50 minutes per symbol! and could easily use more to make them
better). I'm not quite sure it makes sense to put a lot of effort in a
huge granularity of different symbol graphics like this:
HOUSE: #-
/- = House
\- = (was HF)
5- = 50 Hz mains power
6- = 60 Hz mains power
... are there any areas where one house has 50 Hz and the next house
suddenly has 60 Hz? What is the relevancy of this?
B- = Backup Battery Power
C- = Club, as in Ham club
E- = Emergency power
G- = Geothermal
H- = Hydro powered
O- = Operator Present
S- = Solar Powered
W- = Wind powered
... huh? 9 more houses to draw, while somehow signaling which sort of
power source each house has? Will there also be a separate for a
Hydro-powered house which has an operator present, VHF yagi antenna and a
dog?
I'd suggest this sort of granularity and detail could go to the free-form
comment text. We'll need to hire a full-time symbol graphic artist if we
go to details like this. :)
The "generalize old symbols" direction would be more useful. Like when the
current symbolsX.txt redefines \h, which used to be 'ham store', as just
'store', which is more widely useful.
