There is a new Benz store opened in our city,It really attaract a lot of people to see the opening ceremoney.I do not why at the first,but when i walk closer , i found that,there is a machine which can produce the cloud with the Benz logo ,then no matter the people closer or far-away all can see this logo in the sky.I think it is really a good way for the advertise. Here are some picture of that site of activity.You can have a look.It is so interesting. more pictures on w ww.smileclouds.c om
