Intel was promoting its new video conferencing product called ProShare. At the time, video conferencing required specialized hardware and ISDN and so was more of a high end commercial products. The client wanted to show a number of use cases in a stylish way.
The demo CD that resulted contained a walkthrough of a conference center in which the user finds interactive seminars along with video, audio and text-based instruction about a telecomunications product. I used VB to help in this effort.
