a highly relevant message back. Think about the possibilities for this in event marketing. Hand out tradeshow-specific shirts and deliver a custom message with an invite to visit a website, check out your blog, follow you on Twitter, or sign up for a webinar or case study download. These would be great for street teams wanting to create a viral marketing movement. Imagine outfitting retail store employees with these shirts. Text a code, receive a coupon on the spot. Take your phone to the cash register to redeem it.
In a world where people look at what you wear, t-shirts have for a long time been used as a communication channel. The problem is that message couldn't change. Now it can. I really like the possibilities with this.
