This is simply amazing.
I'm impressed.
I didn't think it was possible to get more than 16 colors from the CGA card and here is a demo showing over 1000 colors.
On a stock IBM 5150 PC from 1981
(video via 8088 MPH: We Break All Your Emulators « Oldskooler Ramblings,
from a discussion at Hacker News).
And for those of you who are curious as to how this was done,
there're indepth articles about the graphics programming
(via Hacker News)
and the sound programming
(again, via Hacker News).

The dates are the permanent links to that day's entries (or
entry, if there is only one entry). The titles are the permanent
links to that entry only. The format for the links are
simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are
interested in, say 2000/08/01,
so that would make the final URL:
https://boston.conman.org/2000/08/01
You can also specify the entire month by leaving off the day
portion. You can even select an arbitrary portion of time.
You may also note subtle shading of the links and that's
intentional: the “closer” the link is (relative to the
page) the “brighter” it appears. It's an experiment in
using color shading to denote the distance a link is from here. If
you don't notice it, don't worry; it's not all that
important.
