How about Korean letters, translated they'd say "I wish I had a Gen1". :lol:
And thats a slap on the wrist from Lidl for starting a Gen war.
Seriously though, Korean letters, could work as part of a graphic, you could have "UKHCC" in Korean letters on top, with English translation below it. Or huge Korean, with "UKHCC" in English printed over it. You could have the letter spell anything you wanted, even your name, useful then if you ever have to fill out a form in Korean.
It'd be different, people will stop to look at it.
Also whatever pattern you decide on, make sure the letters are a differnt colour to the rest of the graphics, as it'll be easier to make out UKHCC then.
If I knew how to use photoshop then I'd attempt a design of the above.
