The final design needs to be in-keeping with the Windows8 (Metro/Modern) design principles. This is essentially clean &amp; simple. 
 
Ultimately I would need a splash screen for the App (620x300) and a Logo (50x50)...and other, but we can talk about other formats/sizes after the competition. The logo would probably not include the text. 
 
I have uploaded my current &#39;attempt&#39; at a splash screen for reference, showing the idea of a spy glass and a cloud. Variations of this would be welcome, but I would also be very interested in different ideas. 
 
Ultimately I think it would be nice to convey the &#39;Cloud Search&#39; element, but the important thing is the Metro/Modern design and to not look out of place in Windows8.

Provided lots of designs and responded well to my comments. Very happy with the results.
