Programs

Connect-four: 

Outsmart a program that learns from you as you play this classic game. This is a proof of concept game for evolutionary game learning. It's also a great example of how javascript and perl can complement each other.
Example of: dynamic image movement in IE 4+; game heuristics. Perl-side: simple file manipulation.

Maze maker:

Draws a maze which you must then trace your way through in order to reach a harder maze. My first game. It has multiple bugs, including the fact that not all mazes can be completed. It taught me two things: always use 'var' in front of javascript local variables and don't use deep recursion in javascript.
Example of: uses a old set of image grid functions I created for this and other games; recursion.

Draw:

Lets you draw and save a simple picture.
Example of: very backwards-compatible ( read old-fashioned) way to create dynamic images from grids. Uses the same functions as Maze. Works with Netscape 2+, IE 3+

Animate:

The next step up from Draw. Lets you create a sequence of pictures and animate them. You can save the source of your animation and use it on your site.
Example of: the same image-grid functions from Draw and Maze, with the addition of some nice movement functions.

Hangman:

Old game with a high class vocabulary. Play versus the computer or a friend. 
Example of: good, clean, basic javascript techniques.

Life:

The classic mathematical life simulation with the addition of color-coding for each generation. Very pretty, almost worthy of screen saver status.
Example of: image/text movement in IE 4+, clean, encapsulated coding.

  Calculators ¬

Molecalc:

Displays weight and percent composition for the molecular formula you input. Handy for an intro chemistry class.
Example of: string parsing, recursion

Truth Table:

Quickly makes truth tables for logic statements - saving beginning philosophy students the burden of doing them by hand.
Example of: string parsing and recursion similar to molecalc.

Carbon Calculator:

A calculator and registration form that tells you how much carbon you are adding to the atmosphere every year and lets you pledge to reduce it.
Example of: Object-based, expandable programming, pop-up windows, saving values across pages using frames. Perl-side: converting form data into excel readable data.

Order Form:

A javascript front-end / perl back-end dynamic order form for a music company.
Example of: Good use of objects to create a simple order form that can easily be maintained and updated by a non-programmer client. Perl-side: tricks with perl Formats.

  Miscellaneous ¬

Graph:

An example page for my graphing functions.
Example of: javascript graph objects. Easy to use and incorporate into pages. I've used these functions on many other projects.

Clock:

An animated analog clock meant to be a feature in other pages.
Example of: a flexible and portable clock. Cut and paste it.

Surf:

A cool and tragic automatic internet surfer. I've spent hours with this delving the subconscious of the world wide web. Type in a query or URL to start and it will randomly follow links, backtracking when it hits a dead end. The tragedy is that, with recent security additions, javascript is not allowed to access the contents of other sites. In order to make this program work, you must: a) use Netscape and b) add the line
user_pref("signed.applets.codebase_principal_support", true); 
to the prefs.js file.

Crypt:

A program that uses a super-simple encyrption scheme to encode text. I just noticed that it's developed a problem with carriage returns in IE 4+. If someone knows the new escape sequence, let me know.
