Pi fandom website "Pi Never Ends" needs a logo

This is what a business in United States was looking for in their graphic design

Things I like: visual puns and double entendres, multiple interpretations (looks like something one way, then another thing another way), cleverness, subtlety, non-literalness.

I'm seeking a logo that elegantly communicates the infinite nature of pi. Please do not include the pi symbol itself, unless you have some very creative approach.

Simple and elegant are required.1-2 colors max.

Words can be separate or concatenated: Pi Never Ends or PiNeverEnds

Color palette: http://www.colourlovers.com/palette/1083480/Between_The_Clouds

Please do not use "Cyan Clouds" as this will be the background the logo is placed on. Cyan Clouds may be used for non-border highlights. Read more
