Throughout the twenty-first century, Halley has continued to employ his iconic "cells," "prisons" and "conduits" in his painting, as his primary subject remains the organization of social space. But, Halley explained in 2011, "the nature of the social space we live in has changed immensely in the last thirty years since my project began. When I started my work in the '80s, the limits of communications technology were the telephone, the fax machine, and cable television. In a very short time, we've gone from the era of limited, linear communications to the epoch of the web, Google, and Facebook."
