This coming Saturday and Sunday, Maker Faire will be hosting over 300 "Makers". Here's just some of the commercial exhibitors from the Maker Faire website (not that I expect you to read every single one of these, but just skim the list, you'll some pretty notable and interesting names):
Groups and associations include:
Austin Alternative Photographic Group
Finally, for those of you with insanely fast internet connections you can watch the following promo clip entitled, "Maker Faire Austin in the 21st Century (The movie!)".
For up-to-date info visit the Maker Faire blog. This is the kind of stuff nerds get pumped up about. This is the kind of thing that when ordinary people attend, they discover that they're secretly nerds. Unless you have some really good excuse not to be there, then you should go. This is the now.
