Today is the 50th anniversary of LEGO.

On the Gizmodo site are a list of curiosities, some of which I've copied here:

- There are about 62 LEGO bricks for every one of the world's 6 billion inhabitants.
- LEGO bricks are available in 53 different colors.
- 19 billion LEGO elements are produced every year.
- 2.16 million LEGO elements are molded every hour, or 36,000 per minute.
- More than 400 billion LEGO bricks have been produced since 1949.
- 40 billion LEGO bricks stacked on top of one another would connect the earth with the moon.
- There are more than 915 million combinations possible for six 2 x 4 LEGO bricks of the same color.
- 7 LEGO sets are sold by retailers every second around the world.
- A January 2008 Google search produces 57.6 million references to LEGO bricks.
- There are 55,600 LEGO videos on YouTube.

My first memory with LEGO bricks was some time in the first grade, where I made space ships and giant turtles with friends, whom I engaged in imaginary battles. What's your first LEGO memory?
