Hey, that sounds interesting, we could even make some svg based
wallpapers this way, I am however not sure what the starttime means, and
how it will work for different time zones? If I understand correctly the
starttime is time in seconds since some event in past (unix epoch). But
it would then mean, that if I set the start time to be 0 hour of some
day in US, it will be 12 hour on the opposite side of the Earth and as a
result I will have day at night and night at day in Europe.
