A new interactive Google Doodle celebrates what would have been Jim Henson's 75th birthday on Saturday.

Featuring six digital Muppets replicating the shape of Google, the doodle lets users manipulate them by clicking the hand buttons below the Muppets.

Not only do the Muppets move their mouths and eyes according to the mouse, two of them perform something special -- the pink-bespectacled head loses his glasses, and the far-right red Muppet eats the long-necked green Muppet next to it.

The doodle was made through a collaboration between Google and the Jim Henson Company, using the Henson Digital Puppetry Studio, which touts its immediate real-time performance of 3-D generated characters by a puppeteering system.

It's so fitting since Jim was such a prolific doodler, said Mel Horan, art director at the Jim Henson Company.

His creative process began with a single doodle and evolved into these amazing characters he brought to life. We tried to capture that and merge it with Google's logo.

Henson, who passed away in 1990, created The Muppet Show and the famous puppet characters on Sesame Street, and he took part in breathing life into characters in Teenage Ninja Mutant Turtles, Dinosaurs and Fraggle Rock.

Jim's son Brian Henson, now the Chairman of The Jim Henson Company, recollected his memories with Jim Henson on the Google blog on Friday.

Besides his love for games and gadgets, Jim Henson's life philosophies were embedded into his works.

It was Jim's philosophy to love people not for their similarities, but for their differences, said Brian Henson.

Jim often had a little lesson about the important things in life: How to be a good person. How to believe in yourself and follow your dreams. And above all, how to forgive. If anything was stolen from one of us -- like when the car was broken into -- he would always say, 'Oh well, they probably needed that stuff more than we did.'

Jim was clearly a great visionary. But he also wanted everyone around him fully committed creatively. If you asked him how a movie would turn out, he'd say, 'It'll be what this group can make, and if you changed any one of them, it would be a different movie,' Brian continued.

Every day for him was joyously filled with the surprises of other people's ideas. I often think that if we all lived like that, not only would life be more interesting, we'd all be a lot happier.
