A minor suggestion. I like the layout, and the background, but sometimes the text can be hard to read unless the background is sufficiently dark enough. I've been playing around with applying a shaded but still transparent background to text. Actually, I'm trying to put together another simple layout using this technique for version 3.2. While the clock in your layout isn't actually difficult to read, that's where I applied the shading just to try it out.
I changed the HTML in the Default Property Set of the "clockcentre" cell to:
<div style="border: 2px solid #fff; width: 1px;">
<div style="height: 150px; width: 500px; position: relative; overflow: hidden">
<div style="height: 150px; width: 500px; position: relative; overflow: hidden; background-color: #000; filter: progid:DXImageTransform.Microsoft.BasicImage(opacity=.80); z-index: 9"></div>
<div style="height: 150px; width: 500px; position: relative; overflow: hidden; top: -150px; text-align: center; z-index: 10">
<clock alwaysShowHours="false" format="clock">
</div>
</div>
</div>
For the "COUNTD" Property Set, it's the same except I changed the background-color style (in the HTML above, not of the cell) to "#fff" (white) and the opacity to .30 instead of .80. This makes the shaded background lighter which makes the dark blue clock easier to read.
I also removed the border of the cell. I did this in case the size of any other cell in the same column changes (gets wider) you'll see that the contents of the clockcentre cell will remain at 500 pixels but the border will be wider. It won't look right. By using a div with a border surrounding the other HTML, the border will be the size of the contained content regardless of its size. If another cell in the column gets wider, the clockcentre content will remain the same size.
Anyway, just thought I'd share.
