<p>My idea for logo below.....  Or squarer with black 'leading'? StackExchange icon for comparison:</p>

<p><img src="https://i.stack.imgur.com/F230l.png" alt="4x4 latin square in red and blues with white leading, curved edges and a speech bubble tail"> <img src="https://i.stack.imgur.com/0Iajo.png" alt="4x4 latin square in red and blues with black leading, curved edges and a speech bubble tail">
 <img src="http://stackexchange.com//apple-touch-icon.png" alt="StackExchange icon"></p>

<p>My idea is to combine mbq's 'crossvalidated' logo entry with a 4x4 <a href="http://en.wikipedia.org/wiki/Latin_square" rel="nofollow noreferrer">Latin square</a> and keep a family resemblance to the <a href="http://stackexchange.com//apple-touch-icon.png">StackExchange icon</a>. The Latin square illustrates <a href="http://en.wikipedia.org/wiki/Design_of_experiments" rel="nofollow noreferrer">design of experiments</a>, and also references the <a href="http://en.wikipedia.org/wiki/File:Fisher-stainedglass-gonville-caius.jpg" rel="nofollow noreferrer">Fisher window</a> and hence the "<a href="http://en.wikipedia.org/wiki/Ronald_Fisher" rel="nofollow noreferrer">genius who almost single-handedly created the foundations for modern statistical science</a>". It could also be a <a href="http://en.wikipedia.org/wiki/Heat_map" rel="nofollow noreferrer">heat map</a> representation of a <a href="http://en.wikipedia.org/Contingency_table" rel="nofollow noreferrer">contingency table</a>. It needs a bit of tweaking and I'm not fixed on the colours - the present ones combine red/orange diagonal squares (like mbq's design) with various shades of blue (like the SE logo, and because, as everyone knows, <em>blue</em> is the colour of statistics!).</p>
