Artist Michael Kalish Creates Portrait of Muhammad Ali Using Punching Bags

This artist's tribute to Muhammad Ali floats like a butterfly and swings like a ... punching bag.

Using about 1,300 speed bags, five miles of stainless steel cables and two miles of aluminum tubing, artist Michael Kalish has strung up a massive homage to boxing's biggest legend.

The installation -- titled "reALIze" -- uses punching bags to form a 23-foot-tall portrait of the famed fighter's face.

From nearly every angle, the giant work looks like a mess of poles, wires and hanging speed bags.

But from one perspective, it all comes together to form Ali's face.
