Far be it for us to wish anything but success for the grand "Imperial Tombs of China" exhibit -- the Orlando Museum of Art really needs the money. Still, in the museum's rush to burnish something so impermanent as a traveling show, we spied a mistreatment of its permanent collection -- at least a piece of it that formerly enjoyed a place of prominence. "Ruins XIII," a towering outdoor metal sculpture on OMA's Mills Avenue side, was toppled during the latest museum expansion. And while we can accept the decision to let it lie for the duration of the construction, we were baffled when OMA recently picked it up, trucked it a mile away and dumped it on its side again in a corner of the unpaved gravel lot that serves as satellite parking for its China exhibit. "Ruins" is now strung with yellow tape to keep cars from bumping into it. Why, we don't know; they won't return our calls. But clearly they're not as fond of the old toys as they are of the new.
