Online Presentations

I really injoyed the presentations in class last week.  I think each one of them put Pink's 6 senses (Design-Story-Symphony-Empathy-Play-Meaning) to a good use.  

However, I still have my doubts about Illuminate.  Maybe I need faster Internet, but it seems like it's too clunky.  What are the alternatives?  GoToMeeting?

Note to self:  Explore voicethread some more, looks like it is a powerful presentation tool.
