This is FLAMEbot. He's a heat seeker. Draw the shades and darken the room. Light a butane lighter and FLAMEbot will follow the heat/light source. Hold the flame several inches in front of FLAME's diodes until he catches on. You'll know it when he does cause he will start rolling toward the flame. FLAMEbot will also respond to other light sources so it's important for the environment to be dark. I have attached the original circuit sketch offered via the Parallax website. It's amazing just how simple the design is. Just do a search for the flame seeking boebot and you should find the link. Below is the source code.
