My Dear Mr. Duk:

I am finally back at command central after a delightful family Thanksgiving in Paradise (California). Will record and send the tape tomorrow.

You asked again about map colors and mentioned that you could work with HSB (Hue, Saturation, Brightness), RGB (Red, Green, Blue) or CMYK (Cyan, Magenta, Yellow, blacK). I spent a few minutes with Photoshop and came up with the following chart comparing land and sea values for your current Alex program, the existing Conquest game, and colors I prefer from my OracleCard simulation:

LAND       H   S%   B%     R   G    B      C%   M%   Y%   K%
Alex       120  100  80     0   204  0      81   0    98   0
Conquest   120  100  73     0   187  0      83   0    100  0
Oracle     120  100  53     0   136  0      86   14   100  1

SEA        H   S%   B%     R   G    B      C%   M%   Y%   K%
Alex       240  100  87     0   0    221    98   90   0    0
Conquest   204  100  100    0   153  255    73   30   0    1
Oracle     180  80   100    51  255  255    46   0    20   0
Does any of this make sense? As for patterns, the truly nice ocean wave effects in the Photoshop mockup I did were created by brushstrokes; normal 8x8 pixel Macintosh patterns don't look quite as sharp. One possible compromise: several slightly different wave patterns applied at random. This, of course, would be a low priority; the first step is applying any kind of simple pattern.

I think the delays while scrolling were noticable even before the gridlines went it. For that matter, the current Conquest game is a little choppy for my taste. Anything you can do to improve performance will be appreciated.

It doesn't look like Betsy and I will be able to drive south this December to visit you and Scoville. We'll be busy enough up here. Next week my friends from Montana are flying in to join me for the Newton Developers Conference in Santa Clara. At the same time Bill Lortz will be flying up to San Francisco to attend DECUS. And I will also undergo training at Sybase for their new GUI tool. After that I *may* drive to Montana with a friend. Through it all I am still hoping to make progress on a different smoothing algorithm.

One bit of sad news: Aristippus is finally sucumbing to old age and is now lingering in a Idaho Falls kitty hospital. I'll keep you posted.

Hope you had a happy and productive weekend!

Yours in haste,

Epicurious J.
