Meet the man behind art that leaves Google fans goggling.

The best part of Dennis Hwang's job (assistant webmaster at Google) isn't in his job description. Hwang is also the search engine's holiday artist, creating dozens of theme logos each year. On "Tech Live" we put a face to these Google doodles.

Hwang, a former art student and Google intern, fell into his unofficial job two and one-half years ago when he was asked to help tweak another artist's illustration on the site.

"It's a complete accident but a very fun job," Hwang says.

Who thinks this stuff up?

The 25-year-old native South Korean gets deadlines from a Google committee that meets every few months to decide which special days to celebrate. Those days include everything from Halloween to the kickoff of the Winter Olympics to Korean Liberation Day.

But it's not all fun and games for the illustrator. Hwang gets anywhere from months to just a few hours to dream up a logo.

"We wanted to celebrate Monet's birthday. And I had less than a day. It was a totally spontaneous thing," Hwang says. "I guess because of the spontaneity of it, the rendering was very fresh and people seemed to respond to that."

Not every logo a hit

There are a few logos Hwang would rather forget -- like his birthday salute to artist Pablo Picasso. Hwang says it was just a no-win prospect.

"It was one of the more stressful projects because Picasso's birthday was coming up and I wanted to do a stylized logo around his style. But [as] one of the greatest artists in history, how do you live up to that?"

Then there are the critics

Google users are quick to respond when Hwang hasn't done his homework, like for his doodle celebrating the discovery of the DNA helix.

"I wasn't paying too much attention on the scientific accuracy of my double helix," Hwang admits. "After I posted it, a lot of scientists across the world, a lot of geneticists across the world, were pointing out minute flaws in the illustration."

He ended up correcting and reposting the sketch within a couple of hours. Still, with a worldwide audience watching his work, Hwang tries to take praise -- and criticism -- in stride.

"I'm still not very used to how much exposure my work is getting. It's really user loyalty of Google that's having people care so much about the logos," Hwang says. "But it's definitely the best job!"
