[edit] Summary

A number form from one of Francis Galton's subjects. Note the convolutions, and how the first 12 digits correspond to a clock face. This motif is also found in more recent studies (Piazza et al., 2006) consistent with an environmental influence on the exact pattern of numerical-spatial associations.
