This is a interactive Sculpture project called Cloud created byCanadian artists Caitlind r.c. Brown & Wayne Garrett.  Is was made from 6000 light bulbs that build a giant cloud in the public space.Each of these bulbs is attached to a pull-string, allowing viewers to control the illumination of the structure – like lightning in the CLOUD above them. I really like this work because I do like the result that people can interact with installation in the public space and is actually many people can engaged. So, what the cloud looks like depends on many people’s behaviours . Moreover, I like this installation is not using too much super tech inside of it. I mean a lot designers and artists dive into the technology recently which they try to integrate the tech such like sensors, AI, projection in their projects. I think maybe people over use  technology in their project. I think sometimes just very simple material can arouse people’s emotional resonance. It does not have to be very high-tech. I do love this project is very pure and low-tech but I think is very smart and at the same time it let everyone engage with it and enjoy it. It makes me start thinking I should consider factors in the future when I do a interactive project. Sometimes is more about material that you choose, more about user experience rather than thinking about technology all the time.
