I gave two lectures to the Haifa Linux Club - both had HTML slides and both were done in a relatively partisan way.
I decided that I need a tool to simplify a construction of good looking and functional presentations, so I coded the initial version of QuaD-Pres to fulfil it.
The incentive for QuaD-Pres, and the goals it was supposed to achieve were given in this E-mail .
Later on, after I learned Website Meta Language, I enabled QuaD-Pres to use it, and used a combination of WML and QuaD-Pres ever since.
