A neat idea for an event activity…

I’ve heard of this kind of thing before, but this article by HeadHardHat demonstrates – with pictures – how they ran a GPS accuracy test at a flashmob event. I’d like to know what they used to mark the coordinates!



  1. I was wondering the same thing! lol. seems like a neat little game.

  2. Narcissa, do you know what the results were. The diagram with the pinpoints doesn’t lsit the GPS devices and I don’t know how to get to HHH’s videos to see the full results. I would love to know where phones ended up.
