There's a "green" company in northern California known as the Real Goods Solar Living Center, complete with a water-powered sun dial and, as their highway signage advertised for years, "weird restrooms."
In reality there was nothing too unusual about the restrooms, other than being constructed from recycled materials. The countertops contained small inlaid bits of intriguing colored glass and other less identifiable textiles. But when you've been in the car for many an hour and your bladder (or your fidgeting child) is urging a stop at the nearest "necessary" (as they used to be known), a sign pointing the way to weird restrooms is more than a welcome relief.
Clearly, the Solar Living Center was an early adopter when it came to the creative use of signage. Because once unsuspecting "customers" stopped by to take care of business, the business's attractions took care of them. Children squealed as they placed their hands under the waterfall in the sun dial, parents perused the gardening tools and outdoor DIY section, and soon enough wandered into the store itself, often emerging quite some time later, laden with packages. Not bad for a simple investment in a few road signs. In fact, this is probably one of the least expensive marketing vehicles available for the ROI.
So think strategically weird. Is your business located someplace that lends itself to a pit stop? Are the restrooms attractive? Perhaps you'll want to take a leaf from the Solar Living Center and place signage along the road to pull in traffic. If your draw is a unique product or service, this may be your sign's hot button. For instance, a gift store that sells many unusual items, in addition to clothing and crystals, also features a tarot reader on certain days of the week. "Want a Tarot Reading?" may be all your sign needs to say for the curious to turn in, and end up shopping.
Weirdness can definitely be good for business. Just look at all the people with rainbow hair and pierced body parts…
