Conway's look and say sequence describes itself: 1, 11, 21, 1211, …. The term 11 comes from looking at the previous term 1 and saying "one one"; the term 21 comes from looking at the previous term 11 and saying "two ones"; the term 1211 comes from looking at the previous term 21 and saying "one two, one one"; and so on.


You can choose to make the first term 1, 2, or 3. The term is interpreted by taking each digit as the rotation by the angle with respect to the direction of the previous digit, tracing a path called a vectorgram. A vectorgram is used to visualize the distribution of digits and the correlations between them.
