palo alto research center (parc)

Have visited many times over the last 30 years, quality of work and insights never fail to impress. Not sure how much you could get to see if not an invited guest

The GUI interface was designed and refined (not quite far enough in my opinion) here. I've used the auditorium for SIGGRAPH professional meetings. This place does not give tours to the general public (both good and bad). You must generally know people who work here (an exception where the 8th graders in the 70s who were test subjects). Woodsy (they can't have trees in the patio area due to Palo Alto laws, no shade). Look at it from a distance. My friends who worked here were lucky. They now realize this.
