After reading a book about optical illusions, we made a Thaumatrope with a kangaroo wearing boots and a top hat. And who wants a bit of wikipedia to start the day? 😉
“A Thaumatrope is a toy that was popular in the 19th century. A disk 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 blend into one.”
