For a moment, it looks like trash on a subway grate. Then, the air from the subway below allows the plastic garbage bag to take shape and morph into a giraffe.
"I think we're used to seeing a bunch of trash on the ground all the time, and then to have the surprise of this animal pop out of nowhere is what's getting people excited," Harris said.
Harris said he plans to install more creations, like bears and other animals, when he has time.
And for the record, Harris said the famous movie scene of air blowing Marilyn Monroe's skirt was not his inspiration. It was actually watching garbage moving on the subway grates.
