On March 14th, the world is celebrating all the big imaginations everywhere. This day also marks Albert Einstein's birthday, who said, "Imagination is more important than knowledge." 

Imagination is powerful and limitless, driving creativity and problem-solving, and igniting human development. 

The soldier pictured above is celebrating with A.J. Witt's fantasy-sci-fi book The Source: Origins. He built his very own Medieval helmet . . . can you imagine fighting in that?
