Like it or not, advertising has become a deeply entrenched part of our online experience. Ads--moving, still, or blinking--sit alongside our news, our email, and our Facebook profiles. If you find this visual bombardment less than pleasing, one of the 2008 Rhizome Commissions should be able to help you out. Developed by Steve Lambert with Evan Harper, Addart is a Firefox extension that replaces ad content on given websites with original artworks from a predetermined database. More than just blocking adds like other available 'ad blockers,' with 'AddArt' every two weeks a selection of five to eight artworks (chosen by invited curators) will be available to you. This is not Steve Lambert's first shot at the plight of omnipresent advertising. He is the CEO of The Anti-Advertising Agency and with GRL (Graffiti Research Labs) they recently created Light Criticism, a creative 'rebranding' of some of New York City's LCD screens. The Bus Stop Bench Project worked to the same effect, by covering Oakland city bus stop benches with original artwork, Lambert addressed the passive ways through which we constantly receive images, and highlighted the ease through which this power can be harnessed for good.
