Many would say a moment like this is what the Game Developers Conference is all about.
At the end of his lively lecture, Rovio exec Peter Vesterbacka continued to charm the audience with a rapid Q&A session.
That was before a man named Erin Catto stepped up to the mic.
“Er, um, yes hello. I was wondering, what physics engine do you use in Angry Birds?” Catto asked.
“Box 2D,” Vesterbacka retorted snappily.
“Is there any chance you could credit it on Angry Birds…?”
This time there was a pause. An awkward one.
“Sure,” Vesterbacka reasoned.
“Great,” Catto replied, “I’m the creator of the Box 2D physics engine.”
The crowd erupted into applause.
“I have to talk to you after this,” Vesterbacka said.
