The quarks have been implemented with the so-called Chirally Improved Dirac operator, which obeys the Ginsparg-Wilson relation to a good approximation. We present geometrical and statistical properties of these eigenmodes and eigenvalues.8 pages, 5 figures, Contribution to "Sense of beauty in physics," 26-27 Jan. 2006, Univ.
