Before you say, "Wait, I thought this was home technology?!" hear us out: Instead of using this as a clothing item, you could use it as a home decor item by mounting it on the wall. Use it to write a cute (short) note to your significant other, a word to meditate on, the theme of the day, or whatever you want to put on it to spark conversation. It's a way to use an LED message board in a decorative way. They're $50 each and available at Macy's.
We're not sure how widely available they are, we saw these at Macy's on Nicollet Mall, you could buy them directly from the store over the phone. Also note that these are a limited-promotional item, so if you're interested, purchasing sooner rather than later is a much better idea.
