The kids (or maybe their parents) are going to be lined up at [Nathan’s] front porch to get their turn at playing pumpkin Tetris. That’s right, he built a game of Tetris into a real pumpkin. We thought this looked quite familiar when we first saw it and indeed he was inspired by our own LED Matrix Pumpkin from two Halloweens ago.
