Hello! I'm organizing a group of players who will be available to play casual pickup games via webcam on google hangouts. This method is tested and works GREAT!
Aim your webcam at your cards and see your opponent's cards on your computer screen. It also works well using an iPad/tablet aimed at the table and you view the iPad screen.
The only equipment required is a computer, webcam and gooseneck clamp (or iPad and iPad gooseneck clamp)
