Lego, the company who produce some of the greatest robot and toy kit in the world are celebrating the 50th year of the Lego Brick - the classic 2x4 brick that is the most easily associated with their brand.
As you may (or may not know), I am myself an AFOL or Adult Fan Of Lego. For those who like Lego but are unaware how much their hobby is shared, be sure to go and find out about Lugnet - the Lego Users Group Network. Lugnet is an internet community all about sharing and enjoying the Lego hobby, and has specialist groups for robotics, technic, building mecha, build houses, trains, spaceships and all sorts of other stuff. There are even conventions (although I am yet to make it to one) where people display their amazing Lego creations.
I own a rather large amount of Lego, what is in fact my second collection. I started building Lego kits as a kid, and had a big mixture of technic and space Lego, which I abandoned when I thought I was old enough to leave alone. My sisters scattered most of that collection to the four winds.
I rebuilt my collection with a combination of new purchases, and handy buys from eBay and BrickShelf. I now own the RCX, Cybermaster, Manas, a SpyBotics kit, plenty of space Lego, some bumper boxes of generic bricks, plenty of pneumatic kit as well as the amazing NXT, all of which demonstrate that Lego are still innovating in the construction toy market, and it is all mostly backwards compatible.
For the purists, remember that the studless beams still can act as sockets for normal studs and are compatible with all the technic pins.
These days, I would never again give up my Lego, and although it takes up a reasonable section of my storage, it is one of my prized possessions.
