ZAC Browser

This is cribbed directly from {A}:
Brian Bergstein reports for ABC News about a man who created an Internet browser for children on the spectrum:
"The Zac Browser greatly simplifies the experience of using a computer. It seals off most Web sites from view, to block violent, sexual or otherwise adult-themed material. Instead it presents a hand-picked slate of choices from free, public Web sites, with an emphasis on educational games, music, videos and visually entertaining images, like a virtual aquarium."
