Andrew is a perennial student, informally enrolled at YouTube University. He can't stop designing and tinkering. Recently, he completed a wood-fired brick pizza oven--a barrel design from his own drawing board, replete with removable chimney and mosaic tiles, capable of baking pizzas in 2 minutes and slow roasting meats overnight. It can bake 3 pizzas at once or a whole piglet. His pizza parties usually starts around sunset and lumbers toward midnight, until no one can eat another bites.
