Firenze wall clock, 1996 (1965) Achille and Pier Giacomo Castiglioni ABS plastic, 14 1/4 x 14 1/4" Manufactured and lent by Alessi Available from the MoMA Design Store   Named after the city where the prototype was presented in 1965, Firenze is the redesign of a classical wall clock, stripped down to its basic face. Once again, one has to look for the hidden expressionistic twist: the Roman numeral IV is misspelled "IIII."
