Light bulbs encased in ice slowly melted their way free, sending drops of water falling into black basins below.

The water drops echoed in the dim, cave-like interior of Southern Oregon University's Retzlaff Gallery.

Bachelor of fine arts student Colby Stephens used his knowledge of electricity, chemistry and construction to create the sculptural installation, which will be on display through Jan. 27.

"There's a total reversal of form," he said. "The ice object disappears and the vessel below becomes full."

The title of the exhibition, "Positive/Negative," is a play on both electrical and art terms. Stephens studied engineering at Portland State University before coming to SOU and focusing on sculpture and photography.

"As the electrons transfer from the negative terminal to the positive terminal through the resistor, heat develops. Heat melts the ice, the positive (white) form, and transfers it into the negative (black) space of the vessel below," he explained in his artist's statement that accompanies the exhibit.

Back in February 2010 during a photography class, Stephens suggested that a friend freeze a light bulb inside ice and then photograph the results as the ice melted. She said it couldn't be done, which convinced Stephens to give it a try.

In October 2010, he started months of work to freeze 65 light bulbs inside ice tubes. He can make three at a time, using rubber molds that he made himself.

After each tube is frozen, he stores it in an ice chest set at 5 degrees below zero.

The water used to make the ice tubes has to be distilled so that minerals won't conduct electricity and short out the light bulbs. Luckily for Stephens, a science building on campus has a water distillery.

Stephens is continuing to freeze light bulbs inside ice even as the exhibit is running, melting away his creations. It's a race to make enough ice tubes to always have five suspended in the gallery space.

After the installation went up on Jan. 6, Stephens spent more than 12 hours in the gallery, taking photos every 10 minutes to document the process. When he left, about three-quarters of each ice tube had melted.

Many of the light bulbs are crushed during the freezing process. Stephens estimated he has about a 60 percent success rate. On a recent morning, all three light bulbs that he was freezing had broken when he pulled them out of the freezer.

People who have visited the gallery are usually filled with questions about how Stephens made the installation. They've also commented on the echoing sound of the dripping water, which manages to seem both gentle and eerie at the same time.

Stephens said he had focused on the visual aspects of the installation, and hadn't planned on sound becoming such an important aspect.

"I do enjoy the sound. It's not something I planned on purpose, but it does indicate the transition from positive to negative," he said.

Retzlaff Gallery hours are from 9 a.m. to 5 p.m. Monday through Thursday. The gallery is inside the Art Building, next to the Schneider Museum of Art.

Daniel Kasser photographs

Visitors to the installation should also check out photographs by Daniel Kasser in the Art Building lobby. Kasser, an art professor in California, has blended photos of rural landscapes with mysterious images of mechanical parts that look like they came from industrial and agricultural uses.

In "Western Technosite #78," a part that looks like a mammoth gear is partially embedded in a field, while wind kicks up towering clouds of dust.

'Exploring Being'

In the Marion Ady building near the Schneider Museum of Art, SOU art student Kelle McFarland's "Exploring Being" exhibit features colorful, large-scale abstract paintings on canvas.

"These are process-based paintings," said McFarland, who said she is trying to let go of her focus on the final outcome for a painting. "I've been going through a pushing and pulling process. These pieces really show that struggle. They show the joy and pains of the whole process of art making."

'100 Faces'

In the Meyer Memorial Gallery near the museum, student Ryan McInnis' "100 Faces" exhibit features a chronological arrangement of his portrait paintings. He is inviting viewers to judge which were successful and which were not, and whether he plateaued or continued to improve.
