This proposal has been selected as the winner for the Sister Cities Artwork Competition at the Indianapolis City-County Building Plaza. The plaza is undergoing a redesign and we will begin development of the work after it is completed.

We recognize that the Sister Cities Program enables and promotes the connection of people from different parts of the world with local residents, while highlighting the diversity of culture in Indianapolis. Our proposal mirrors this effort by encouraging multiple levels of interaction between passersby and people in the City-County Building Plaza.

The name ΔLLOY is derived from the symbol Δ (delta), which mathematically represents change, and the word Alloy that is a metal made by combining two or more metallic elements, especially to give it greater strength. Rather than developing a static piece that in some way represents the interaction of various cultures, our proposal is intended to be the catalyst for actual human connection. A dual-sided network of pixels, which take the form of the Δ symbol, encourage cooperative use by people outside the plaza with those inside. As users pass by, the pixels will physically “change” to trace their movements, however only half of the project can be affected by each side. In order to create an entire reaction across the surface, users from both sides will have to “come together” and actively communicate. Our hope is that this project will connect people from various cultures by stimulating conversations through simple acts of playfulness.

The kinetic network is created through a series of repeated modules. Inside each module is an individual sensor, that if tripped will engage lighting and a very simple flapping movement of the pixels. Each unit operates independently and will be created with off-the-shelf analog components that do not require any actual processing. The overall field effect is accomplished by the users’ interaction as opposed to complex computing through the electronics. The two sides of the network will have very different compositions based on material selections, and with the addition of the interactive lighting in each component, the project will transform during use at night.

The streetside conceptually represents the diversity of cultures existing in the city of Indianapolis. Pixels in this elevation will be composed of mirrored acrylic, reflecting the user and surrounding environment. The image on this side will be constantly changing based on the various people that are passing by and an ever-changing backdrop. As sensors are activated, the image breaks apart and the reflected colors shift relative to the movement of each pixel. Active use inside the plaza will visually affect half of the piece, and this interaction should entice passersby to enter and experience the project from the opposite side.

As the public enters the plaza, the dual nature of the piece becomes apparent. This face references the global community and the variety of cultures that are brought together through the Sister Cities program. A mosaic colorway was developed using multi-color printed polycarbonate. The ∆ symbol is apparent again as pixels are clustered into a larger sets of four. When the installation is engaged the larger symbols (representing various cultures) begin to move and reflect light, and the smaller components (representing the people that create them) are realized.
