The Takaratomy Kotoridayori Humming Bird proves that solar power is not just for calculators and the hopeful/naive who believe it's not too late to stop global warming anymore. Solar technology has found a greater purpose in this world than determining the order of operations or allowing our children to "live" and "eat".
Solar power allows the Humming Bird to sing sporadically through the day, adding a general sense of peace and well-being to co-workers. Plus, the bird senses vibrations from those walking by, and serenades them into tranquility. For a mere $25, you can teach the world to sing, one cubical at a time.
