You can build your dream Lego model and if they like it, they’ll even make special bricks!
For example this Irish Pub in Greenwich Village by Sean Kenney:
Noah is NOT seeing this link!!! 
There was a bit on the news about this. A kid here, about 11 years old, sent in ten or twelve designs, and two were accepted by Lego and are now in production. We didn’t have Lego when I was a kid (everything was Meccano back then - I think my dad liked to play with it more than me), so I never really saw the attraction of Lego, but its a real hit with kids nowadays.

Just the other day, I stumbled on this:
http://www.henrylim.org/Harpsichord.html
This guy to about a gajillion legoes and built a playable, full-sized, functioning harpsichord. It’s entirely legos but for the strings. The only “cheating” he did was to re-shape a few of the pieces with a blow torch and saw.
Talk about too much time on yer hands. ..
I’ve actually played this “creation” of Peter’s:

it needs amplification - Peter is looking into doing that with the Mindstorm processor. Everything is made with Legos, except the strings, which are nylon harp strings.
You do need to be careful what you tune it too - too high a note and the darn thing collapses on you!!!
Very frickin cool IYAM!!! I had a buddy in highschool whose dad made Harpsichords. I got to spend hours playing them. One of my favorite instruments!
Holy harpsichord Batman. It’s amazing it could withstand the string tension. Did you see the mosaics and the stegasaurus?
WOW.
Wow! Too cool!
My son, now 17 won the area LEGO contest several years ago by building a model of our local Shell station. It was sponsored by the area Shell distributers. Much fun, and although he didn’t win in the third step up larger contest, he did get to come home with a big, expensive, electronic LEGO set… and it saw much usage. Cool stuff, though decidedly over priced, IMHO… of course, that keeps them from ending up in the trash. 
At my ex-wife’s house is a round cardboard can filled with Lego-like plastic blocks from the 1950s. They were made in the USA and are called “Elgos”, I kid you not. They seemed to be the American answer to Legos. I always meant to sell 'em for a presumed fortune as they are intact and in decent shape but this was before Ebay days. Came from her uncle’s attic along with a vintage train set.
My father had a bunch of Eglos that he gave to me when I was a kid…ironically enough, that was how I got into Legos…
Now the name reminds me of waffles somehow…
I also never had legos when I was a kid. They seem like Harry Potter to me–something everybody loves but I can’t figure out why.
