CEDIA Expo 2011 is history, but the memory lingers on. Many manufacturers go to great trouble and expense to dazzle showgoers with their booths, and I always photograph a few of the best ones as I wander the floor. My favorite this year was the Klipsch booth with its floating translucent columns encasing LEDs that provided an ever-changing light show. But it wasn't the only booth that caught my eye…

KEF's booth featured this elegant crystal chandelier sparkling high above the show floor.

SpeakerCraft always constructs a great booth with lots of organic elements, and this year was no exception.

Runco's WindowWall tiled display was assembled in a sculptural array showing stills from classic black-and-white movies, forming a great juxtaposition with all the modernity surrounding it.

This open-top view of a Mark Levinson No. 53 monoblock power amp ($25,000 each!) was not an architectural element of Harman's booth, but the internal red-LED illumination looked way cool.

Sony's booth was topped with these large projection screens showing abstract colors in slowly evolving patterns.
