Art jam: where a bunch of people get together, with or without talent, and daub paint on a canvas. Art spam: where galleries send lots of e-mails about exhibitions. Art cam: Black and white arty film Art ham: arty pig with a beret Art tram: trundling tram with arty things to encourage people to think about art in Western district and elsewhere. The public art project 'Art Marking Boundaries' is trundling around tracks on Hong Kong Island. Step on board and see the designs of local artist Tse Ming-chong and other members of the creative team of people from three organisations - the Working Group on Greening and Beautification Works in the Central and Western District, the Hong Kong Arts Centre and Public Art Hong Kong. Collector and historian Cheng Po-hung hosted a cultural heritage tour of Central and Western district on March 7. The idea of the tram is to inspire residents to think about the changes in the coastline and cityscape, and provide an 'aesthetic delight' for the public. The Art Tram will be running until April 3. So, get tramming!
