I just bought a couple hundred large posters of the earth from space that I'll be putting up on overpasses for the next couple of months. It'll be like all those flags that went up after 9/11, only going up during the tragedy instead of after. Some I'll post with messages, others will go up alone. In the meantime I'll be looking for slogans and messages that go well with pictures of Planet Earth over freeways. Send me your ideas and if I like them, I'll use them. The three best ones will win cash prizes of $1,000, $500 and $250 and have their words read by literally hundreds of thousands of people. Your message can be anything you like, but the issue I'm most concerned with is global warming, particularly what is happening in the Arctic. Messages should be short, smart, fit well into a rectangle and look good over traffic. They can be meant to go either with the earth posters or without, so long as they make people think. Original ideas are preferred but not required and, apart from the right to post them publicly, I make no claim to any entries as intellectual property.
