yep, i agree with mingshey, the shape of the greek miniscules simply reflects a shorthand for writing the capitals, and as i think i've already suggested earlier, their shapes seem a bit arbitrary if you print
them but totally make sense if you running-write
them. try writing out the whole alphabet... i only take my pen off the paper 8 times, on gamma, kappa, lambda, twice on pi, tau, chi and psi. you'll notice in particular that the "flow-on" connector provides the first stroke for following letters in e.g. kappa-lambda, lambda-mu, omicron-pi (top stroke), sigma-tau (top stroke), phi-chi, chi-psi (up-stroke). if you do this, you'll also see my letter stroke order. cheers, chad.
