A small Vancouver company has created an iPad app based on A Charlie Brown Christmas that attempts to capture the magic of the 1965 TV Christmas classic.

Company founder Calvin Wong always loved the TV special and wanted to create a version children could interact with that stayed true to the original.

"You don't want to mess up a masterpiece," he said.

His company, Loud Crow Interactive, made its first foray into children's apps with one that introduced kids to the Peter Rabbit stories of Beatrix Potter.

Then, the company that owns the rights to Charles Schulz’ Peanuts comic strip came calling.

Curt Petrovich reports on what was involved in creating an interactive animation with the Peanuts characters, and getting the rights to use children’s voices recorded more than 40 years ago.
