An annoying thing about going to concerts is that often someone much taller will stand in front of you, blocking your view of the band. This situation is especially bad for short people, who never get to see anything except the heads and shoulders of the people in front of them.

Crowd-leveling pedestals solve the problem of height inequity. The floor in the venue is replaced with a grid of square hydraulic lifts, that can move three feet below or three feet above the baseline level of the floor. Everyone in the audience stands on a square. Once everyone has a place, the pedestals either raise or lower themselves depending upon their riders' height. Taller people sink slightly under the floor, while shorter people get a boost. Eventually the entire audience is arranged in a gentle slope, so that no matter how tall you are, your eye level is always slightly above the head of the person in front of you.

Of course, at energetic shows where people like to mosh and dance, it can get pretty tricky for the floor to maintain its equilibrium. It's therefore recommended to wear knee pads and crash helmets to such shows, to save oneself from injury from the inevitable falls.
