Collect a few dozen glow-in-the-dark paint samples, some duct tape, a Geiger counter, and a Hazmat suit. You know, for safety.
Drown the rug in a vat of radioactive waste and watch as it glows with an otherworldly energy. Don't worry about the whole "glowing with an otherworldly energy" part, that's just a side effect.
Use a jackhammer to drill holes in the rug at precisely 4.7 inch intervals. This will add a nice, industrial aesthetic.
Place a large, black, industrial-looking drop shadow under the rug to really make it pop. This will make it look like it's about to fall off the wall at any moment.
