I've heard stories about it, but has anyone simply built a "tower" out of lego pieces and bricks? By a tower I mean lots of bricks on top of each other.
It's actually quite a common thing to build. So much so that TLG has held a number of tower building events at their theme parks and at other locations. Here's a photo of what I believe is the current world record. This was completed in Prague and is 32.5 meters tall.
