Add-Art 1 Favorite 

Add-Art is a free Firefox add-on which replaces advertising on websites with curated art images. Created with the support of Eyebeam, Rhizome, Add-Art releases new art shows every two weeks and strives to feature contemporary artists and curators.

The plugin works alongside AdBlock Plus, which blocks online ads, and simply replaces that blank space with art images. AdBlock Plus is the most popular of the thousands of available add-ons for Firefox with 18 million total downloads (as of May 2008) and over 250,000 downloads last week.

For many, replacing ads with blank space would be enough. Add-Art attempts to do something more interesting than just blocking ads – it turns your browser into an art gallery. Every time you visit the New York Times online or check the weather you’ll also see a spattering of images by a young contemporary artist.
