That's why we want you to rebrand them. Your brief is to create a logo
for BP which shows that the company is not 'beyond petroleum' - they're
up to their necks in tar sands and deepwater drilling.

The winning logo will be used by us in innovative and exciting ways as
part of our international campaign against the oil company.

We're after the best ideas and concept, not necessarily the slickest
logo. So if you're not a professional designer don't worry. If you're
the overall winner we're offering you a day with a top graphic designer
to transform your idea into a final product.

We're inviting you to design them a new logo that's more suitable for
their dirty business.
