涂鸦文化是什么？？每每走过废弃的巷子看到这个👇不知道你会不会像我一样心头一阵狂喜奔腾呼啸而过呢👇👇👇👇（下附自己献丑合的录音，加音乐的哦）

街头涂鸦文化首度出现在1960s'America，现在已经扩散到纽约，柏林，伦敦，哥本哈根等大城市并逐渐被人们接受并演变成一种艺术。

它是一个城市年轻的标志，它代表激情，躁动，不安，叛逆，他来源于我们内心最深处的声音，色彩鲜明铿锵有力，个性张扬。你可以不认同它，但你永远无法忽略它！

如此炫酷狂拽的技能我做梦都想get到好不好！然而呆萌的腐国首都伦敦却永远在任性

LONDON'S fastest-changing art gallery is hidden in a sunken ball court on a housing estate in Stockwell, southLondon. On a sunny Sunday afternoon six or seven men, mostly in their 30s, are busy painting the walls with new designs. They have put up cartoons, names written in elaborate, multicoloured lettering and clever perspective tricks. Tins of spray paint and beer stand on the ground;ladders lean against the paintings.The atmosphere is not unlike that of a golf course: a mix of concentration and blokey relaxation.Graffiti painting is traditionally a daredevil pursuit. Teenagers dodge security guards to put their names on trains and buses.But over the past decade that has all but disappeared fromBritain's cities.Between 2007 and 2012 the number of incidents of graffiti recorded by the British Transport Police fell by 63%.A survey by the environment ministry shows that fewer places are blighted by tags than ever.Graffiti are increasingly confined to sanctioned walls, such as the Stockwell ball courts. In time the practice may die out entirely.The most obvious reason for the decline in tagging and train-painting is better policing, says Keegan Webb, who runs The London Vandal, a graffiti blog. Numerous CCTV cameras mean it is harder to get away with painting illegally. And punishments are more severe.Once-prolific taggers such as Daniel Halpin, who painted his pseudonym Tox all overLondon, have been given long prison sentences. British graffiti artists who want to paint trains usually go abroad to do it these days, says Mr Webb.A generational shift is apparent, too.Fewer teenagers are getting into painting walls. They prefer to play with iPads and video games, reckons Boyd Hill, an artist known as Solo One, who in effect runs the Stockwell ball courts.Those who do get involved tend to prefer street art to graffiti proper (which purists define as letters and names, however elaborately drawn).Some have gone to art school and want to make money from their paintings.The internet means that painters can win far more attention by posting pictures online than they can by breaking into a railway yard.Taggers and graffiti artists mostly grew up in the 1980s and 1990s.Those men—and almost all are men—are now older and less willing to take risks.We can't run away from the police any more, says Ben Eine, who turned from tagging to street art. The hip-hop culture that inspired graffiti in the first place has faded.Video games and comic books provide more inspiration than music. Graffiti may eventually disappear. But for now the hobby is almost respectable. Mr Eine says he has lots of friends who used to paint trains.Now with wives and children, they paint abandoned warehouses at the weekend. It has become something to do on a Sunday afternoon—a slightly healthier alternative to sitting watching the footbal
