Admit it: The first time you drove past that giant, angled black cube beside Insterstate 5, you thought the actual kids' museum it belongs to was inside. Later, maybe you caught the light shining through it, realized it was hollow, and wondered what the point was. Did the designer of the Discovery Center just really, really like Pink Floyd and somehow figured kids could learn about the actual dark side of the moon? Turns out it's actually a massive solar-panel array that powers the museum?if you pay admission, you can find out all the groovy details and, yes, even get inside it. If solar power is indeed the future, could it be that one day we'll all have trippy black cubes attached to our homes? We can but hope.
