HOUSTON, Texas -- Houston is about to learn a new $10 word: "Zoetrope."
It's an optical toy invented in the 19th century, predating the animated film, and one which shows images in rapid succession, creating the illusion of motion.
That is the official definition from Houston First, which is bringing 12 giant zoetropes to Avenida Houston in a free, family-friendly, illuminated musical installation called simply "Loop."
