Graphic Design Brief
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.
Updates
I'm removing the provision for including pi in the logo, as too many pi-based logos have lacked great creativity. If you have an extremely creative way of representing Pi, go for it, but otherwise please don't pursue that direction. I will update the brief.

Project Deadline Extended
Reason: I've added some more explanation of what I'm looking for, so I'm extending the deadline.

In the interim, I've been using the regular Bigmouth font in lowercase as a word mark. If you like, you may like to integrate it into your designs.

Please demonstrate your logos against a background of RGB (115,200,169)

After seeing enough designs, I don't like the look of concatenation words, so please don't do PiNeverEnds or pineverends anymore.
That leaves pi never ends, PI NEVER ENDS, and Pi Never Ends
