New front page image

Spent a few minutes playing with a new front page image. Aurelius suggested that the tag lines should be a little more action focussed, and I was concerned the old image had too many colors and lines (it's mandatory for lots of white space in these Web 2.0 times).

Hopefully it's a bit clearer to read and understand now.

Would you agree? I'd be interested in your feedback on the front page. Is it clear what OSA is about? Any ideas for further improvement welcomed.
