Dear VMCAI 2004 participants, I apologize for the demos that didn't work during my talk. The reason turns out to be an update to the Windows Media Player, which my computer apparently attempted to download --- on its own --- the previous evening. The download didn't go well, and my machine ended up pointing all .avi and .mpg files to that version.... Sorry... In a partial attempt to make up for this, please got to the following web page (which I will leave in place for several weeks): http://www.wisdom.weizmann.ac.il/~dharel/TEMP/Venice/ On it I have placed the two smart-playout demos for the C. elegans system I was planning to run, as well as the British humor piece that attempts to show the effect of carrying out a simulation not on the real thing (the real thing is the man driving, and the simulation is his wife...). Thanks very much for your attention. David Harel
