I'm no fan of display advertising, either in web banners or "out of home" and I certainly try not to participate in it. Logos and brands are already everywhere, why should you and I become unpaid ad space when manufacturers splash their logos on our stuff? Well, now there's another solution to this problem: Logo Removal Service, a company (or perhaps an art project) that "renew[s] any and all goods through special transformation methods."
That means they cut the logo right out of your t-shirt and replace it with a new piece of fabric that may or may not match the original item. Fancy stitching completes the look. You never know precisely what you get when you send logo gear in to LRS, but I think it's safe to say it'll be a unlike anybody else's.
I find it pretty easy to get blank t-shirts in the first place, but there are some items that are unavoidably logo'd and require obliteration, covering up, or in extreme cases, not buying in the first place. In any case, you've got to work with what's available or make your own - possible with clothing but pretty hard with consumer electronics. I applaud LRS for encouraging creative re-use (do they call that upcycling these days?) over of disposable consumerism.
