Powered entirely by solar energy, your brilliant Einstein figurine will ceaselessly think, consider, and ponder, tapping his finger to his temple in time to the flow of his expansive thoughts. Place him on your bookshelf, windowsill, or dashboard so you always have a companion in contemplation. When the sun is shining, Einstein will be a reminder of the importance and power of thought (as well as renweable sources of energy!).
