Logo for Pocket Vocabulary Coach - helping make you smarter

Pocket Vocabulary Coach

We help our subscribers build a huge vocabulary to impress people with their large repertoires of unique words. Our company puts those words right in their pockets via their mobile devices for them to use. We send a word of the day every day to people's phones. We are an educational messaging service. It's not imperative for us to have a character. But we DO want a logo that is more than just stylized PVC letters. The logo needs to communicate that with our service we help make you smarter via mobile phones.

Idea suggestions (this has been added after the first 6 designs simply submitted stylized letters "PLC"):
A pocket with a phone sticking out of it.
A pocket with a person sticking out of it holding a phone and a dictionary.
A sequence of infographics: dictionary -> word -> phone -> person looking at phone and getting a bigger brain/becoming smarter.
Image of a phone jumping out of a dictionary and into a persons back pocket.
Additional creative ideas are welcome.

Our sister company is Pocket Literacy Coach. Our logo is here: http://pocketliteracy.com/ (it's the words plus the lil character). We want something clean and crisp but also something that is scholarly-looking. Our service is a mobile subscription for folks who want to build their vocabulary - students, lawyers, teachers, scholars, etc.
