Were you dancing at the time?
I imagine it’s not as easy in terms of producing the template video to match your body type (and maybe agility) and then to set up the projection just at the right distance. Conventional wisdom might also say that you learn dance moves better by copying others and that’s why you get floor to ceiling mirrors in dance studios.
These kids have a bad enough lot in life by being born to and probably being negatively influenced by irresponsible parents. They probably deserve more care and individual attention than a throwaway question like this.
