A DIY website’s HahaBird user Nathan Pryor turned his pumpkin into a fully functioning Tetris game. So-called Pumpktris is rigged with 128 LEDs while its stem is used as a joy stick to control the falling figures.
Nathan even put up a detailed explanation of his work process and the creation of the light matrix for anyone who’d be up for the challenge. After putting the lights together and figuring out a code to actually operate them, Nathan had to carve a pumpkin to put the construction inside. Lastly, he unscrewed the redball of the joystick to replace it with the pumpkin’s stem, and gave this new device a double-edged name of “joystem”.
