The redesign of this web site is simple, colorful and vibrant. Live-action characters greet and guide children through the site's interactive features. Sesame Playlists, a blend of videos and games, can be shared with friends and filtered by subject, theme or character. My Street is a customizable space for children and their caregivers. The site hosts more than 400 Flash-based games and activities and a growing archive of 3,000 episodes. But the star may be the Playsafe application, which prevents children from navigating to other sites on their own.
