Here are lamps that could put you in the right mood. The Sun Lamps are a work of Rotterdam designer Arnout Meijer. They can be adjusted to create different moods throughout the day. Depending on the color you go with, these lamps can relax you or help you focus better. These look downright trippy to me. This collection of lamps includes a narrow table lamp, a round table lamp, and a wall lamp. Wish I could own one.
