The founder of our company is a BBQ enthusiast. He has a special Pizza oven in his vacation house that is awesome....

He also is a huge fan of the Big Green Egg BBQ. They have an optional electronic heat control module "The BBQ GURU" or something like that...
Anyways I guess he wrote the software for it. A couple of my friends have them and swear by them that it's the best BBQ set up out there.

There is even a smart phone app to control the device. Maintains temps within TWO degrees!
