"Surrey, England-based artists Heather Ackroyd and Dan Harvey create large-scale living portraits made out of grass. Known for their grass &amp;lt;a target=&amp;quot;_blank&amp;quot; href=&amp;quot;http://www.trendhunter.com/trends/hsbc-wimbledon-grass&amp;quot;&amp;gt;Wimbledon billboards&amp;lt;/a&amp;gt; created back in 2008, they have since been compiling a more intimate and personal series to exhibit. Like nature&amp;#039;s own photographic negative, they create these stunning portraits by exposing plots of seedling grass to light through a custom-made photosynthesis device in order to make the grass grow in different shades, from yellow to green. In just a small window of time, the faces in the grass can be perceived before fading away again. When talking about their chosen medium, Harvey says, &amp;quot;The grass has a certain importance because of the simplicity of the blade. By nature it slightly grows towards the light.&amp;quot;"^^<http://www.w3.org/2001/XMLSchema#string>
