Over the next few days, some of you may notice a truck driving around the D.C area with a mysterious slogan on the back:  "You are on an island," spelled out in tall neon letters. It's not an ad campaign for a winter getaway deal to the Bahamas, but a conceptual sculpture by Alicia Eggert, a Maine-based artist who is having a solo show at Artisphere through Feb. 2. As part of that exhibition, the rolling sculpture will be in town through Sunday.

You are (on) an island: West Yorkshire, England 2013 from Alicia Eggert on Vimeo.

Eggert's mobile statement is actually designed to deliver two distinct messages. The word "on" periodically disappears, changing the words from "You are on an island" to "You are an island," before changing back again. It's characteristic of the artist's playful, often text-based work, which typically involves open-ended meaning that alternately reveals and conceals itself.

Eggert will be driving the vehicle, pulling over at various locations to interact with viewers. You'll find her truck parked all day Thursday in front of Artisphere, where Eggert will be feted with a public reception from 7 to 10 p.m.
