This is definitely fall out from our trip to Legoland. The Lego website offers Lego Digital Designer. Download the file and install it. Viola, you have the pleasure of living vicariously, without actually having to invest in a Lego set and buying only those special ones that really interest you.
No, its not that easy. The compulsion to build something without actually having to break your head and pay a ton is not easy to ignore. Hats off to the geniuses who sit and break down anything and everything into Lego bricks and then put them back together again.
The software offers the full range of brick shapes which you can put together and then send to Lego, so that they can put the pieces together in a full set, which you (or anyone else) can then buy off their site.
