Zorap, Web-Based Video Chat
Zorap web pages are multi-party multimedia environments. Video from your webcam and audio from your microphone, photos, music and video from your own computer are shared to tens of your friends via a Zorap Server. Web content, including YouTube and other video sites are similarly shared, all in an exciting and customizable drag-and-drop interface.

Electric Magic implemented the Mac-specific portions of the Zorap web plugin, supporting Safari, Firefox and other modern web browsers.

Knowledge Forum 4.6
Knowledge Forum 4.6's minor version number change belies just how different from its predecessor it really is.

Under the hood KF 4.6 has moved from using ZDBase for its backing store, instead using a tuplebase. This makes it possible to split HTML page generation into separate processes, potentially running on multiple front end machines. It also restores support for a rich client application, now written in Java, using ZTSoup to efficiently communicate changes in the tuplebase, whether made by other clients or by the web interface.

Web Browser Plugins
ZooLib's UI code requires only that there be a ZFakeWindow-derivative at the top of the enclosure hierarchy. In the distant past ZooLib included implementations of ZFakeWindow for Mac control panel cdevs, HyperCard XCMD windows, MacroMind Director XObject windows, Zoom closures, MacApp views and of course still does for ZOSWindows.

It was thus relatively straightforward to implement ZFakeWindow_NSPlugin, which translates between the Netscape browser plugin and the ZFakeWindow APIs. What was actually more difficult was finding a decent implementation of the plugin glue code and header files. In 2002 there wasn't anything that would work with current compilers and with current browsers, so most of the effort was in putting together ZNSPlugin, which is a usable implementation of the glue.

ZooLib
ZooLib is an Open Source (MIT License) C++ library that makes it easy to write one set of source and build an application for Windows, Mac and UNIX. It provides a foundation suite of facilities that in essence form a virtual operating system API, and wide range of higher-level facilities that build on that foundation.

Knowledge Forum 3.0
Knowledge Forum 3.0 took advantage of major enhancements in ZooLib that let the client be released for Windows as well as Mac OS. Much of Knowledge Forum 2.0 had been built around the Mac-only Zoom framework, and so had to be reimplemented. The parts of Knowledge Forum 2.0 built with ZooLib were simply carried forward, with refinements and enhancements.

NPainter

NPainter is a suite of classes that provides a MacPaint-like interface, but supporting indexed and true color, across all platforms supported by ZooLib.

ZOSWindow: Abstracting OS Window APIs

ZooLib had always maintained the ZFakeWindow abstract interface between user interface elements and the hosting environment. This allowed ZooLib UI widgets to be used within MacApp applications, standalone applications, Control Panels, XCMD windows and XObject windows. It worked very well.

However, when the portability axis was across platforms rather than hosting environments there was the potential for a lot of replication and ugly code in ZWindow, the standalone application derivative of ZFakeWindow.

So, I abstracted the interface to OS-windows, placing it in ZOSWindow, and modified ZWindow to use a ZOSWindow, rather than be conditionally compiled for different platforms.

Knowledge Forum 2.0
Knowledge Forum 2.0 is a computer supported collaboration environment designed to foster the growth of knowledge building communities. It's based on the CSILE project, developed at the Ontario Institute for Studies in Education and is published by published by Learning in Motion.

DigiPhone
The publishers of Digiphone, a VOIP application for Windows, took a shortcut to getting Mac compatibility - they (indirectly) bought NetPhone from Electric Magic, and had me add support for DigiPhone's communications protocol and audio codec.

NetPhone
In 1994 the Internet was just starting to be available in people's homes and offices. NetPhone was the first application to support what's now known as VOIP (Voice Over IP) without requiring a high-speed connection.

Measurement in Motion
Measurement in Motion is a pioneering math and science analysis and investigation tool. It lets students take measurements from real-world video footage, then tabulate, graph and derive secondary measurements from their data. Conversely, students can generate data algorithmically and superimpose it over video to provide visceral confirmation of hypothesized behavior.

Marrakech

Marrakech took the hypermedia concepts I explored in WorkSpace and applied them to the problem of managing workflow and assets for multimedia development.

Creative Whack Pack
The Creative Whack Pack was a software version of Roger von Oech's famous creativity-enhancing deck of cards. Scott Kim collaborated with Roger on the application's design, which had some neat features including a system-wide hot-key that would bring up a random card, a click on which would seamlessly invoke the application. The app's window also showed animated transitions between screens (dissolve, rotate etc).

WorkSpace
WorkSpace was an interesting application that took user interface ideas from Andy Hertzfeld's Servant, and hypermedia ideas from all over, and combined them into a personal information manager that used the web of links between entities to represent meaning. It was never released as a product, but was where I first started creating ZooLib, and formed the basis of Marrakech and ultimately of Measurement in Motion.

MediaMaker
MediaMaker was a ground-breaking application that provided a Finder-like interface to manage multimedia content, coupled with a timeline for assembling that content into a finished production. It controlled laserdisc players, VCRs and CD-ROM drives, managed video overlay cards, played AIFF files (no mp3s back then), MacroMind Director presentations and displayed PICT files (no JPEG either).
