Here is a cool juggling simulator that helps to teach you how to juggle.
When I was in high school I tried out for a part in a play based on Commedia dell Arte a type of comedy popular in Italy in the 1500s and 1600s, performed by specialty troupes who improvised on stock characters in stock situations. One of the character had to juggle so I taught myself how to juggle. I didn’t get the part but I still can juggle three items.
