Konrad, maybe I've missed it, but how do you treat nasalized vowels
in the system?

I think it is quite easy to draw accurate pictures of the runes in
the various maniphestations and save them in e.g. .bmp format.
When I made the 18th century Dalecarlian runes on the site
http://www.geocities.com/jepe2503/hogsvenska/dalrunor.html
I just used MicroSoft's Paint and saved them as .bmp files. I think
they are at most 1K each.
