                <p><strong>Hi!</strong> This is a <strong>demo application</strong> that shows how you can do pattern recognition on pictures or images using the PyBossa framework in Crowdcrafting.org.
               </p> 
            </div>
            <div id="1" class="modal-body" style="display:none">
                <p>The application is really simple. It loads a photo from <a href="http://flickr.com">Flickr</a> and asks you this question: <strong>Do you see a human in this photo?</strong></p>
                <img src="http://farm7.staticflickr.com/6109/6286728068_2f3c6912b8_q.jpg" class="img-polaroid"/>
                <p>You will have 3 possible answers:
                <ul>
                    <li>Yes,</li>
                    <li>No, and</li>
                    <li>I don't know</li>
                </ul>
                </p>
                <p>
                </p>
                <p>All you have to do is to click in one of the three possible answers and you will be done. This demo application could be adapted for more complex pattern recognition problems.</p>
