Kidz, it's the 50th anniversary of filing of the first patent for a Lego plastic brick today. This toy is so old that *I* remember playing with these bricks as a child. I think the compelling factors behind them are that the sets can be snapped together into infinite combinations only limited by your imagination, once built they provide playability, and it's hard to poke your eye out with them. The last factor is for parents as I know that poking someone's eye out is probably an attraction for many kids. I did want to raise a toast to Ole Kirk Christiansen, inventor of Lego, for many hours of fun and fascination. A timeline of the Lego company can be found on Gizmodo.
