A thaumatrope is a toy that was popular in Victorian times. A disk or card with a picture on each side is attached to two pieces of string. When the strings are twirled quickly between the fingers the two pictures appear to combine into a single image due to persistence of vision. One of the most common example of thaumatrope features a bird on one side and a cage on the other. (Animated version)
Joseph Jacques Omer Plante (January 17, 1929 – February 27, 1986) was a Canadian professional ice hockey goaltender. During a career lasting from 1947–1975, he was considered to be one of the most important innovators in hockey. He played for the Montreal Canadiens from 1953 to 1963; during his tenure, the team won the Stanley Cup six times, including five consecutive wins. Plante was the first NHL goaltender to wear a goaltender mask in regulation play on a regular basis. He developed and tested many versions of the mask (including the forerunner of today's mask/helmet combination) with the assistance of other experts. Plante was the first goaltender to regularly play the puck outside his crease in support of his team's defencemen, and he often instructed his teammates from behind the play. Plante was inducted into the Hockey Hall of Fame in 1978, was chosen as the goaltender of the Canadiens' "dream team" in 1985, and was inducted into the Quebec Sports Pantheon in 1994. The Montreal Canadiens retired Plante's jersey, #1, the following year.
