This is a neat Flickr Mash-up. In the centre of the screen is a colour wheel. You can select any colour on the wheel and pictures from Flickr are inserted in Thumbnail size surrounding the colour wheel that are completely the colour you chose. For example I chose a bright yellow and got pics of corn, sunflowers yellow raincoat. In addition your can manipulate the intensity of any colour you choose.
All these wonderful pictures filled with colour and texture - you could copy them and arrange them in a pattern to use for a quilt a la Kaffe Fassett.
