Apple Store retail locations will be hosting Apple Camp for free for kids aged 8 to 12. It spans three days on various dates (1.5 hours per day) and teaches campers how to shoot footage, create an original song in GarageBand on an iPad, and put it together in iMovie on a Mac. The camp ends with the children presenting their finished iMovie at the Apple Camp Showcase.
