Art Circles for iPad was created by Art.com. This free app allows users to discover a world of art images through wheels of art. There are six inspiring wheels including colours, nature, art movements, inspiring insiders, superzoom-texture and words. You simply select a wheel and then tap to view the gallery. My daughter loves searching through the images, so will students of all ages! Please note, this app required internet access.
If you do not have an iPad Art.com have on online resource that is also fabulous. It is called Visual Search. On Visual Search you can can either select a style that you like and then the site will find similar pieces of art work for you, or you can select match an image. With match an image, you can upload an image of your own or enter a link to an image and then the site will locate similar images of you to view.
