I was finally able to upload some photos.  Above is an example of our first challenge to write one's name with LEGO bricks.  It spells "Vivian".

Our second challenge was to build the tallest "earthquake proof" structure possible with 100 bricks. 

We worked together in groups of two and rebuilt the structures multiple times to make them taller and stronger.  The "earthquake table" is behind the structure above. 

The teams weren't opposed to breaking down the structure to start all over and make it better.  That attitude is critical when problem solving.
