Hand-Painted Grateful Dead Dancing Bear with Lightning Bolt Mood-Light Bulb. This Bulb casts a Dancing Bear on one side and the Lightning Bolt on the other side the room projecting the colors and image onto the walls, or a lampshade. Any style of white lampshade works! "Sometimes the lights all shining on me, Other times I can barely see! Lately it occurs to me, What a long strange trip it's been!" - Grateful Dead.
