For street artist, all New York is his canvas

James De La Vega has a message for New York  and he\'s writing it all over the city. A cigar-smoking street philosopher, De La Vega leaves mysterious sketches, sayings and exhortations in chalk on pavements, bike lanes, even garbage piles. He\'s so prolific that while few know his face, the sidewalk seer has become one of the Big Apple\'s most famous artists. \"Become your dream,\" urges his signature motto, scrawled over the line drawing of a fish leaping from a bowl into a drinking glass and the signature \"DELAVEGA.\" The curious words and designs, always in white chalk, appear outside subway stations or on sidewalks, often popping up overnight. Instead of a bowl, there could be an hourglass, a love heart, a raincloud, spear or other objects, with the fish sometimes replaced by a snake or turtle. The accompanying words are brief, ambiguous. Like, \"Sometimes the king is a woman.\" Or, \"Be mindful if your mind is full.\" Every day, teeming crowds of commuters walk over the temporary inscriptions, then rain eventually washes them away. De La Vega is relentless: he said in an interview that he can execute about 100 a day. \"I\'m planting seeds,\" he said. New York has a rich history of street art, but De La Vega  who prefers to be addressed by his last name  insists he has nothing in common with the destructive impulses of graffiti. He began in his home neighborhood of Spanish Harlem 20 years ago with murals on abandoned buildings that were meant to \"beautify, to give people something to be proud of.\" Then along came the now iconic fish, \"Become your dream,\" and the rest of the growing repertoire. The fish, he says, \"are not meant to beautify. These are strange things.\" De La Vega works at great speed, leaving his trace along streets in a pattern that seems to come instinctively, depending on where he is. Recently he has taken to working his way through the asphalted paths and roads of Central Park, which in summer teems with tourists and armies of fitness-mad locals running the Loop. De La Vega walked briskly against the torrent of runners, pausing briefly to sketch, throwing used stubs of chalk into the grass and reaching for fresh sticks. Mostly the runners went right past, but some lost concentration for a second, glancing at the 37-year-old, whose body is emblazoned with tattoos reading \"Become your dream,\" \"Legends never die\" and the Spanish version of his catchphrase: \"Realiza tu sueno.\" \"This is a niche audience,\" he said with compassion. \"They\'re very vulnerable. They probably have doubts about the future.\" A few hand movements later, he\'d sketched a fish with long legs running across the path of the constant human flow. \"This stuff sinks in,\" he said. In the middle of the flow, a runner half-turned in surprise on recognizing the signature on the tarmac: \"Hey, De La Vega!\" A little later, a woman also did a double-take when she saw the fish. \"We like your art. My kids love it,\" she grinned. De La Vega makes little attempt to explain what he\'s doing and refuses to speak about his background, an attitude only adding to his underground image. Alongside the Central Park boating pond, he drew a fish in a bowl with a heart above and an empty bowl alongside. A group of children on a school outing stopped to watch. \"It\'s some kind of duck,\" one said. \"No, not a duck. It\'s a bunny,\" said another. Walking on, the bemused children found the next installment  De La Vega often draws in series, almost like unspooling cartoon footage  and this time the fish was running from the bowl. At the final scene, the children found fish leaping from both bowls and meeting in a kiss midway. \"Oh, it\'s a fish jumping,\" one of the children finally realized. \"We got a whole story,\" another said. \"It\'s a love story,\" a third said. Beaming, the children began to clap. Already, De La Vega was far ahead, drawing on the ground. He drew a fish running uphill toward a sack of dollars. Next, he drew a fish in a bird cage watched by a free bird. \"Drawing for me is a way to explore,\" the soft-spoken artist said. \"My intention is remind people that they don\'t have to be so powerless  that they can construct dreams.\" Then he took his chalk and walked on.
