Just dance. Find five differences in every two photographs of people dancing. Picture gallery and game.

Dancing have become a popular activity, thanks to several seasons of Dancing with the Stars and Just Dance games. As we have learned watching some stars on Dancing with the Stars show, dancers do not have to be really good at dancing to enjoy it. Simply listening to music and moving, doing any kind of movement, could pass for dancing.

Dancing also does not have age limits. Babies dance before they could walk and older ladies love their square dances on Saturdays. The joy of movement is universal for all ages. (Just Dance games have various versions for kids, teenagers and adults for that exact reason.)

Dancing is also a great way to exercise. Just dancing will help with cardiovascular activity and make most people sweat. But unlike other exercise routines where the same few movements have to be repeated over and over again, dance provides almost unlimited choices for movement. More choices means less boredom.

Another plus for dancing is dressing-up. Imaginative colorful costumes and make-up are a lot more acceptable on a dance floor than they are in a fitness club.

The pictures below are of people doing just that: enjoying fun group dances. All of them participated in the Halloween Festival at the Castle of Muskogee in Oklahoma.

To make things even more interesting, I have duplicated every picture and created five differences on the second one. See if you could spot what's different in every picture.
