        <p><strong>Visualize Somerville 2</strong> (#VisSom2) combines technology, activity, and community into a large scale interactive installation. This event was hatched by the group <strong>Optexture</strong>: a think tank of dreamers, coders, makers, and futurists.</p>

        <p>We created Visualize Somerville last year, and this year have upped the ante by providing interactivity for all participants.</p>

        <p><strong class="highlight">Visualize Somerville 2 is the attempt to disrupt our views of current day technology.</strong></p>

        <p>Everyone uses their personal devices, Ipads, smartphones, to keep connected like never before. But this also has a downside, as we also get lost in our own world and forget the world around you. How many of us have turned to our phones when we are traveling? Nervous?</p>

        <p>Visualize Somerville 2 takes that device, and brings new meaning to it: direct involvement and collaboration with the climbers, other painters, and the art you create as a collective.</p>

        <p>This is also a Masters Capstone project for a member of Optexture (Jon MacLeod). Thank you for coming, and enjoy!</p>
