In the document
http://www.convict.lu/Jeunes/ultimate_stuff/Making%20your%20own%20RCX%20sensors.pdf
you find a paper-disk with grey gradient. The document was part of my
presentation at the 2005 Annual Robolab Conference in Austin/TX. There was a
second part
http://www.convict.lu/Jeunes/ultimate_stuff/Making%20your%20own%20RCX%20sensors_part2.pdf.
I don't remember, if those documents ever have been available to the public.
