Casual observations of a new sculpture in Regina suggest the work is raising a few eyebrows.

The art work, a row of highly reflective monoliths, is set by the entry point to the city's airport.

Some people told CBC News they are not sure what it is supposed to represent.

"It looks like something  that sends a moving message, but what the message is, I don't know," one person said.

"It looks like a bunch of sticks," offered another. "I don't know what to say. It looks like a skeleton or something."

Reflective buffalo spine

While work crews finish installing what will be a total of 17 steel structures, one of the display's designers, artist Paul Raff, explained the steel pieces represent the spine of a buffalo and were designed to reflect Saskatchewan's sky and cast shadows.

Raff said he believes art should challenge people.

"Before they say they like it or they don't like it, or it's a good idea or a bad idea, live with it a little while," Raff told CBC News. "Get out of your car and walk around it. Think about it. Look at how it changes in the light. look at how it reflects the sky."

The sculpture was commissioned by the city of Regina.

Once the installation and landscaping is complete, the total cost for the art will be $200,000.

Raff said people's initial reaction may be "What is this?" but he expects the work will grow on the community.

"I can imagine 20 years from now, after it becomes very much part of the identity of the city, if anyone talked about taking it down, there'd be a protest," he said.

The work stands in place of a sign that said "Welcome to Regina."
