In 1966 Joan Archibald walked out of her house and never returned, changing her name to Kali and taking up photography. During the subsequent decades Kali became more and more reclusive, obsessively photographing the monitors hooked up to her house's extraordinary Closed Circuit TV security system, and making notes and drawings of the nocturnal 'events' she witnessed overnight. After she passed, her daughter's husband Len Prince, a noted photographer in his own right, spent the next two years archiving and organizing the prodigious output of the eccentric and brilliant Kali.
