a high resolution photo of plumbers standing inside a giant, stainless steel drain pipe at a trade show. They are about halfway down the drain pipe. They are dressed casually. A "BLÜCHER" booth representative in a blue shirt is pointing out features of the drain. There is a screen integrated into the inside wall of the drainpipe with technical information on it. The plumbers are engaged and fascinated by the immersive experience.  --ar 3:2
