Pictures artists staged their own images or copied or cut out others already in existence. The viewer took them in separately, in sometimes paradoxical waves: an original image, then the manipulations of it, then the places where image and idea intersected. This created a crucial perceptual glitch that irony and understanding filled.

'Untitled' is a time machine that can transport you to 1992, an edgy moment when the art world was crumbling, money was scarce, and artists like Tiravanija were in the nascent stages of combining Happenings, performance art, John Cage, Joseph Beuys, and the do-it-yourself ethos of punk. Meanwhile, a new art world was coming into being.

Decades ago, Gerhard Richter found a painterly philosopher's stone. Like Jackson Pollock before him, he discovered something that had been in painting all along, always overlooked or discounted.

When money and hype recede from the art world, one thing I won't miss will be what curator Francesco Bonami calls the 'Eventocracy.' All this flashy 'art-fair art' and those highly produced space-eating spectacles and installations wow you for a minute until you move on to the next adrenaline event.

I wish I could write about shows outside New York. I often feel like the last person to know anything, because I almost never get to leave town, and when I do, I tend to go for three days max. Seeing between 30 and 40 shows a week in 100 or so galleries and museums takes up nearly all my time.

To engage with art, we have to be willing to be wrong, venture outside our psychic comfort zones, suspend disbelief, and remember that art explores and alters consciousness simultaneously.

The art gods cooked up something special for James Ensor.
