This is an advanced customization feature for programming musicians
extending the ball bounce's sound behavior. It disables locally
provided sound and enables a TCP/IP socket server, listening at
local port 6668, which streams human readable ascii long integers.
To see these numbers, run telnet localhost 6668
from the command line. For example, MAX/MSP can be used - even
from a seperate computer - to convert the balls' bouncing to MIDI
Note: not all security configurations allow programs to listen
for Internet connections, and firewalls also block port 6668 unless
you change the settings.
