This was a very ingenious way to to publicize the Nikon’s new COOLPIX S1000pj which has an inbuilt projector so you can project photos you’ve just taken onto any surface. To make this known they got the pop act Helicopter Boyz who as far as I can tell are only popular because they wear helmets with propellers on them. They got them to go and do a live performance at Yomiuru Land with cameras strapped to the back of their body, which would project onto the screen behind them. This had very nice results.
