Bizarre is in the eye of the beholder.

With modern architecture, that can mean just about anything.

Some of the extraordinary edifices above were designed to entice a reaction -- contemporary museums and exhibition centers come to mind -- while others astound by their mere existence.

The most controversial are the buildings inspired by whimsy; designed by architects with free rein to exercise their creative impulses on ordinary spaces.

Whether you consider the buildings above awe-inspiring in their architectural complexity or hideous monstrosities, there's no question they capture your attention.
