I wish I were there:
"Word is the robots are the stars of World Expo 2005. Japanese robots of various designs serve functional roles here as multilingual information guides, security guards, garbage collectors, and floor cleaners."
"The Toyota exhibit has a two-part robot show featuring a robot jazz septet that marches into the 800-seat arena and plays ''When the Saints Go Marching In." Then follows an elaborate movie and floor show with nearly a dozen single-passenger robot vehicles, cavorting dancers, and a trapeze acrobat twirling from the ceiling."
Followed by:
"...corporations have acknowledged spending between $2 million and $30 million each on [their exhibits] ..."
Wow.
