"The server also has a Logitech QuickCam connected to it and aimed at the 
player. After every round of three darts the graphical client requests a 
snapshot to see the player's reaction to the shot. The dart server takes the 
snapshot and uploads it to the web server. The client then gets the snapshot 
from the web and displays it on the screen. The most recent snapshot can be 
found at the DartCam web page."
