"The last 24 hours were just extraordinairy. It was like Chinese calligraphy, where the monks take ages to mix the ink and then - bam! - it all happens in seconds."
- Bono on the making of the No Line On The Horizon album, 2009
The cover art for No Line on the Horizon is a photograph of Lake Constance, taken by Japanese photographer Hiroshi Sugimoto; titled Boden Sea, it is one of 200 pictures in his Seascapes collection. The image was the inspiration for Bono's lyrics on the track "No Line on the Horizon".
