Checkerboard…
In reading up about Olithink, I recalled my own not-too-good Checkers program that I called “milhouse”. It doesn’t really work very well, despite all my attempts to make it work. I dusted it off, and was reminded about its many shortcomings. Perhaps some day I’ll fix it. But I did dust off a checkers font I found, and made a nice looking checkerboard image anyway…

Addendum: Got the font from here.
I recall burning three or four weeks of a sabbatical getting Saccade.com on the air with Wordpress. So much tweaking…
