The Maker Faire is an opportunity for amateur makers of all things, from arts and crafts to robots to everything in between, to showcase their work and be inspired by others of a similar mind. There is one held each year in San Francisco and one more recently popping up in Austin, Texas.
The Austin Texas Maker Faire is being held this year from October 18th and 19th (the San Francisco one occured in May. The deadline for submissions is September 4th (a little over a week from now!). Anyone who is interested in submitting or just going should definitely check it out.
I have unfortunately never been able to make it to one, but have had several friends attend or present at these fairs, and aside from some parking issues have always heard good things.
