Artists Jennifer Allora and Guillermo Calzadilla have taken an ATM machine and installed it into a twenty foot tall pipe organ. The piece is called Algorithm, and when a transaction is made the pipe organ responds with a series of notes based on the buttons pushed by the user.

The piece was shown at the American exhibit of the Venice Biennale last summer, and commissioned by the Indianapolis Museum of Art. The music generated by the organ is composed by Jonathan Bailey. When the piece was shown, viewers were free to make their own ATM transactions, making the work interactive.
