One of the best things I ever did to ease my travel pains was to buy a shiny silver carry on bag. It's not fancy — or at least not expensive — but on the rare occasion I have to check it instead of stuffing it into overhead, I never have a problem picking out which bag is mine on the conveyer.
That's half the notion behind "DotDrops", a line of luggage from France's Artoyz, which allows you to customize hard-sized bags with a grid of colorful "microdots" — no, not acid, nor film, Formica, rifle scope, nor horse — plastic chits that are affixed permanently to the front.
My first instinct was to bristle at the lack of reconfigurability — especially since the bags aren't cheap, with the smallest starting at € 300 — but I've since warmed to the idea that they'd be somehow more durable if they were attached with stiffer stuff.
The web site implies they're France-only for the moment, but patents have been filed! in the US, Japan, and China.
