Originally envisioned by the client as a "Wave Wall" consisting of a single wave mounted on a wall, I took things a few steps further and created two waves that intersected and were actually suspended from the ceiling at the highest point in the store. One section of the wave actually dipped down into the first floor and could be walked beneath.
Simple construction-grade 2x4 lumber was ripped down into 2x2s and then cut to various lengths. One wave twists at a consistent 12 degrees, while the other was created completely free-form as it was installed. This installation was absolutely massive, and somewhat difficult to capture in a single photograph! Some fisheye lens shots seem to give a bit of sense of scope.
This was on display in the Urban Outfitters store in Omaha, NE for the better part of a year.
