One idea is to make a rainbow in the shape of a check-mark. The rainbow could be photo-realistic but even more beautiful if possible, and still minimalistic. On the right (long) end of the check-mark, you write &quot;OK-Display&quot;. I&#39;d like the &quot;OK&quot; part to relate to the round button - perhaps it could be a negative circle. The text color could be gold or silver. For readability, the text should not be too small. 
Regarding what fonts I like, check out www.ok-display.com. 
 
This is just an idea, other ideas are welcome too. 
 
If possible, the logo shall reflect the following values: 
* TRUSTWORTHY &amp; SECURE 
* USER FRIENDLY 
* LATEST TECHNOLOGY

The logo I got was all that I hoped for and more! I&#39;m happy that Kunjan Virani joined my logo contest! Many thanks!
