Here's a fun tool for landing page optimization. Actually, it's more fun for you and me as 'testers'. The way it works is that you given a short period of time to give your opinion on a certain design (graphic, logo, etc) or overall webpage layout.
You earn karma points for each design you 'test'. It's fun.
If you're a designer/developer, Fivesecondtest helps you fine tune your landing pages and calls to action by analyzing the most prominent elements of your design.
