Gradient roundrects, drawn in canvas, or assembled out of lots of little divs. [more] [visit]

Embed a JavaScript console in your page, for debugging. Firebug and other more recent applications render this obsolete. [more] [visit]

Print the source of any JavaScript value, for debugging. Firebug and other more recent applications render this largely obsolete. [more] [visit]

Overlay text onto the canvas element. [more] [visit]

JavaScript Bezier rendering and animation. [more] [visit]

An online regular expression workbench, with code generation for JavaScript, PHP, Python, and Ruby. [visit]

See the finite-state automaton that corresponds to your regular expression animate as it runs on an input string. [more] [visit]

Use iCal or Mozilla Sunbird to browse the logs of a subversion repository. [more] [visit]

An spiffy online viewer for subversion logs. See the work and faces of the OpenLaszlo team, or point it at your own repository. [more] [visit]

A Rails plugin for integrating OpenLaszlo on the client side with Ruby on Rails on the server. This plugin includes scaffolding, library modules, and generators for generating REST controllers and OpenLaszlo applets [more] [visit]

A Ruby gem that interfaces to the OpenLaszlo compiler. It allows you to compile OpenLaszlo programs from within Ruby. [more] [visit]

A game to be played with Google. Unfortunately, Google Search doesn't have a REST API. Fortunately, Yahoo does.… (Image credit Remy Charlip) [more] [visit]

A visualization of your del.icio.us tag posting activity, over time. [more] [visit]

An interactive visualization of the relative frequencies of a^mrⁿgh (aargh, aaargh, arrgh, etc). [more] [visit]

PackageMapper traces your FedEx, UPS, and USPS package routes on a map. I built it for personal and family use; you're welcome to use it for as long as it stays up. [more] [visit]

Flash Troll Generator is a timesaving tool for Flash-haters. Mentions of Flash always draw the same response; it seemed a shame to waste humans on writing them. [more] [visit]

Storybase is a user-editable ontology of stories and characters. It stores an RDF-like ontology of entities and relations. [more] [visit]

html2db.xsl converts an XHTML source document into a Docbook output document. It provides features for customizing the generation of the output, so that the output can be tuned by annotating the source, rather than hand-editing the output. This makes it useful in a processing pipeline where the source documents are maintained in HTML, although it can be used as a one-time conversion tool too. This was written as part of the OpenLaszlo doc pipeline.

An open source platform for creating zero-install web applications with the user interface capabilities of desktop client software. I am the Chief Software Architect, was responsible for the XML tag language design, wrote the initial tag and XML compiler, and lead the teams that wrote the compiler and developed the open source release.

static-preview.php allows you to preview files that you edit on your server's filesystem, without storing them in the WordPress database. It is intended for the case where you have access to the file system of your web server or a staging server capable of running php. It allows you to use a text editor such as emacs to edit a file in one window and preview the results in another window. This gives you more full-featured editing than the web browser, and a faster edit-preview workflow cycle than copying between a text editor and and the WordPress Writing web form.

My blog. Essays on software, life, and elementary math education. The most-cited entry is The IDE Divide; the one where I failed to name AJAX is Serving Client-Side Applications, which followed Web MVC. [visit]

A cross-platform 2D graphics and rendering library that was acquired by OpenWave. [wayback 1, wayback 2]

An online multiplayer roleplaying game with artifical agents. This included one of the first Scheme interpreters in Java. [wayback]

Python libraries for compiling, minimizing, and determinizing Finite-State Automata. [visit]

A simple chart parser (<100 code lines for the parser itself).

A Python interface to the WordNet database of word meanings and lexical relationships. [visit]

Dylan was an object-oriented programming language based on Smalltalk and Scheme. I was the project lead for the Hula development environment, and contributed to the language design and implementation. [visit]

A graphics rendering and geometry engine that shipped with MacOS 7. I worked on this at Apple Computer. [visit]

A program that simulated video feedback. I licensed this as a screen saver for After Dark. This technique is now a staple of media player audio visualizations. [visit]

A test bed for manipulating virtual textures, haptically rendered with a force-feedback joystick. This was my wife's thesis work; I created the software system.

Storyspace was a hypertext authoring and viewing environment, before the web. I implemented a hypertext text editor for it.
The company and program still exist; I would be amazed (and horrified) if it still used any of my code.

Using duals to tile the plane with octagons, pentagons, and other interesting patterns. I originally implemented this as a Macintosh program; the version here is a more recent port to Java. [visit]

Menu Editor was a WYSIWYG tool for editing MacOS menus. Menu Madness was an investigation some alternate styles for MacOS menu layout and appearance. Spheres was a port of the Sun screen saver to MacOS. Dragger was a startup extension (init) that implemented solid and translucent window dragging. Tiles and Truchet were mathematical visualizations. [visit]

An award-winning arcades game for the Commodore 64. I was the initial programmer. [visit]
