Amazing Tron Dance

This is a video of 8 people that wore costumes that were lit up electronically. They used the costumes by pressing a button that would turn the costume on  or off . This would look like an illusion because there was more than one person on the stage so when one person turned off their costume the person across the stage would turn on their costume. So it would look like the person moved across the stage quickly. This blew me away, it was cool how the people could look like they were moving so fast. Also, it was so synchronized and if one person messed up it would look odd, but they didn't. The dance was cool because it was quick and the movements were agile, because they flowed well.
