Hi! Here is my initial entry to your contest. Though light bulbs are a pretty common element, they really get the point across if they are done in a clever way. This design uses a clean, simple, and memorable lightbulb created with a G for Greenthink. The lightbulb is a common symbol for thinking and ideas, and it's also a great ambassador for environmentalism. I'm happy to play around with the concept as well as the colors and font if this idea really turns you on! And yes, I guess intended the pun. Thanks so much!
