Here's my favorite photo. I took it in Chicago's Millennium Park a couple of years ago during a break from a conference. It's a little girl playing in a fountain. I have no idea who she is. Look at her face. She's filled with the joy of the moment. She doesn't know how the fountain's pumps work or how the rebar supports the structure. She doesn't know what the shafts or flanges for the pumping and piping underneath are rated for or if they passed the test.
