continue to search for (and exploit) places in which you'd never think to find an ad, it makes sense to scroll a few plugs through an item that the vast majority of us spend at least a few hours per week touching. That item, dear friends, is the handle of the tried and true shopping cart, and apparently, Modstream is hoping to install bars with scrolling displays onto buggies and allow companies to beam in messages wirelessly. The system works by allowing outfits to access a web-based profile, enter in a given message, and transmit the ad to participating stores. As an added bonus, the setup enables said companies to change up their messages on a whim and keeps us shoppers guessing as to what clever line is coming next. Now, who's down with hacking this thing to scroll through our favorite RSS feeds?
