|a card trick||
Basically a graphics experiment, but it does include a long-range day-of-the-week calculator. The trick itself is just silly, but Im a bit fond of the card backs, which are my own attempt at the old different-face-upside-down pictures. (Why dont most computer card games show the card backs both ways?)

Translates an email address into an HTML link, using an encoding that reportedly works with any browser, but is not recognized by most webcrawlers. Part of my anti-spam efforts.
|Random string generator||
Generates random strings in a wide range of lengths useful for creating deliberately-obscure addresses and filenames.
Generates a Gregorian calendar for any year in the range
271,815 BCE (B.C.) to 275,754 CE (A.D.);
also warns when the result may be inappropriate, or just plain silly.
