Imagine a crane game with a front and side web camera that lets you play it remotely from anywhere in the world and you actually win the toys inside! What if this can be set up for children's hospitals or even for anyone in the world to try their skill over the web and then choose which charity or children's hospital to send the toy they just won? This would be a simple hack with a Raspberry Pi and maybe an Arduino. The web server would serve up the web camera video and let them click on arrow buttons or even use the arrow keys on their keyboard to move the crane. The server back end script could then interpret those arrow presses into the same electronic pulses as the joystick on the game does.
You could even set up a paypal or similar pay system that lets people try over the web with all the money going to charity and to buy more toys.
