Read the data and convert it to binary numbers. Use teddy bears for encoding the data. Each teddy bear has another color which represents a sequence of numbers, e.g. yellow is 1010101011101, blue 10101011010101010101010 and so on. We have 16777216 color possibilites with the normal rgb or cmyk color mode. I believe that is more than enough to encode the data (altough I didn't check it). Easy isn't it? ;)
