I am interested in visualization, user interfaces, security
usability, typography, tinkering, and science,
medicine, and technology in general.

- A weather radar display for the Tesla S console.
- My experimental authentication app, 105
is now available in the iTunes app store. I look forward to feedback;
- iTeX, high quality document formatting for the iPad and
similar devices. This is a document format and a free app on
to be in itunes. The project includes
- An attempt to make a PDF reader especially suited to reading
- access to arXiv and Project Gutenberg
documents formatted for the iPad and other tablets,
- semi-automated creation of LaTeX versions of Project Gutenberg
- Better passwords, a problem that is likely to plague
us for a long time. I would like to make authentication easier,
stronger, and more fun. Current approach: trying to convince users
to memorize one passphrase to rule them all, protecting a smartphone
wallet. Also, trying to convince authentication providers to ease
up on the world: the eye-of-newt password rules aren't helping
- Can redaction (especially bad redaction) be used as
a typographic tool to
enhance interest in a document?
The Second Edition is available in several languages.

It is more fun to have written than to write.

The thumbnail reveals more information, data, and a gallery
of some interesting visualizations of the Internet.
a very wide panorama I made with Carlos Scheidegger. The technique
uses orthographic projection, but the film industry calls it
slitscan. There are a number of terrific examples
There are even some air travel-based images though none, I think,
capture the distance across the continental US.

I've developed a
new way to see movies, and I
am looking for movie owners interested in seeing their movies
visualized this way.
Web page redesign:
Some of the web pages on this site
have not been updated since 1995. It was time to explore
and some typographic options.

Science Museum Exhibits.
I have worked on several science museum exhibits
over the years, starting with the original Digital Darkroom
at the Liberty Science Center,
something I developed with Gerard
Holzmann in the early 1990s at Bell Labs.
There are several new exhibits
now, mostly debugged, and available for the asking, including
What Does Sound Look Like?,
How Long Does it Take to Win the Lottery?,
an upgrade for the Chattanooga Children's Discovery Museum,
and a color blindness simulator.
Many other projects over the years,
including some favorite projects
from early in my computing career.
These Internet maps have appeared in dozens of books, magazines,
posters, and papers worldwide. Our technology remains at Lumeta,
so you should contact Lumeta if
you wish to use the images. I am
always willing to discuss them with interested parties.
Recently, AT&T put up
Internet maps at
the Washington airports for the 2009 inauguration. These
versions are not available outside of AT&T.
I am still interested in the visualization challenges these kinds of data pose,
but am not working on it much.
- Some useful notes to myself on
how to do things, that might be of interest to others. I use
these things rarely enough that I forget the details.
- An and an even
family time lapse and
old project queries for which I invited specific feedback.
