Google's logo right now is made of Lego bricks, commemorating the 50th anniversary of the introduction of the bricks.
According to Wikipedia, it's not the 50th anniversary of the company (it's much older), but the brick system as we know it today was introduced in 1958.
I grew up with these toys. I had (and have) a ton of them, and many an afternoon was spent annoying my parents with the sound of me digging through a large box, looking for just the right piece, and many messes were made constructing and reconstructing all kinds of items, and generally leaving special pieces laying about, for quick retrieval, or "I might need that later."
I rarely made the model depicted on the box more than once. It was more fun to build other things. It makes me kind of sad that there are so many pieces now that are good for only one thing, the picture on the box. It was a lot more fun when a bunch of nondescript pieces went together to eventually form something recognizable, and then those same pieces could be used to make something completely different.
Was Lego a huge part of anyone else's childhood? Anyone still play with them?
