Looks like on line 87 of SimpleSerialArduinoscope.pde it assigns the port to
the first Serial port it finds. If your UNO is not that first serial port
(possibly because, for example, you also have your FTDI cable hooked up and IT
is the first serial port) then it won't establish the connection properly. (It
would probably be best if there were some mechanism for selecting which serial
port it attempts to connect to the Arduino on, rather than having it be
hardcoded like it currently is.) In the meantime, try playing around with your
serial port connections and maybe you'll find a combination that lets it read
the Arduino.

On Ubuntu 11.04 the serial port of the Adurino UNO is /dev/ttyACM0 .
Unfortunately the Processing environment doesn't recognize this port. See:
http://code.google.com/p/processing/issues/detail?id=634
After symlinking the USB serial port to another name
sudo ln -s /dev/ttyACM0 /dev/ttySA0
I got it working.

That issue is apparently fixed, and some people say changing the line to
port = new Serial(this, Serial.list()[1], 115200);
(subscript 1 instead of 0) solves the problem, but that seems hacky.
I'd be happy to write a patch that tries looping over available serial
connections if someone can give me a hint how to build SimpleSerialArduinoscope
from source. I've tried various combinations of javac and ant commands but
haven't gotten anywhere.

You can view the source in Processing when you open the example. I think I'd
eventually like to have this all be user-initiated (user selects correct serial
port) but for now, you can just set it to use a differnt port by replacing 0
with whatever serial-port you want to use on teh line that looks liek this:
port = new Serial(this, Serial.list()[0], 115200);
