comment Plotting problem
Your error message is saying (I think) "Coordinate (...) should be a triple of numbers." The points can't be plotted because vN doesn't seem to produce any numbers, just Norm' expressions, which causes that error.

comment Is there a Mathematica barcode reader?
@belisarius I tried to adapt your code to make a "barcode reader", using ImageCapture feeding into your code function via "FrameRate" -> 5, "CaptureAction" -> (capture[#] &). Unfortunately my computer's camera couldn't get the barcode in focus, neither could I hold the item motionless - my arm isn't strong enough apparently. I went down to the local supermarket hoping to access their lasers but they haven't got Mathematica installed at the checkouts so was unable to test the idea any further... :)

@belisarius Yep, that works. In future I'll always bring my white flanks with me... :)

comment CMYK colours changing
Ah, I see what you're doing now - you're displaying the system color picker to sample the RGB screen colour. I couldn't work out how to display the picker from Mathematica's drawing tools... :)

Try CMYKColor[0, .83, 1, 0]? I can't seem to reproduce your image here, strangely...
