Cadence of Diversity is a joyful mural - rich with expressions of many cultures that are balanced with an underlying theme of connectedness.

The 100-foot-long mural is painted on a concrete wall just south of Seventh Avenue on 38th Street in Rock Island. Working with more than 50 Augustana students, Peter Xiao - a professor of art at the college - led the mural's development and execution throughout much of 2009, completing the work in the spring of 2010.

We received 116 entries in our 2014 Photo Contest in four categories: Fun in the Sun, In the Garden, Summer Nights, and Heat Wave. We're happy to present this selection of winners.

The Lindsay Architectural Sculpture Park is a grouping of structural forms derived from historic styles of buildings and homes in the Quad Cities. The park is - in turn - visually engaging, playful, and educational. It is located along the Riverfront Parkway south of the Village of East Davenport.

The park's layout feels organic. Its overall circular shape is crisscrossed with walkways that lead one past - or through - 10 primary groupings of structural forms. The largest of these structures is a 30-foot-tall limestone tower. Its slate roof is constructed in the style of the Victorian towers and turrets built in the late 1800s.

The Col Ballroom, at 1012 West Fourth Street in Davenport, is 100 years old this year. No other large ballroom in Iowa has reached a century of continuous operation. For that matter, neither has any ballroom in Chicago.

During the past century, the sign in front of the Col has been changed several times. The installation of a neon sign during the Jazz Age signaled a change in the cultural role of the ballroom. It was replaced when rock 'n' roll became king, re-made when rock went psychedelic, and duplicated when there wasn't a prevalent new direction in popular music.

Each sign had its own aesthetic, stylistically shaped by its era. Each is interesting in and of itself. However, they are all the more fascinating when we see them as a reflection of the sweep of changes in popular culture throughout the century.
