David Forbes wanted to build something really cool to wear at the Burning Man festival. So he re-purposed a relatively simple flexible circuit board covered with LEDs. He made the first with 30 rows of four LEDs each and then contracted a manufacturer to build 175 more of them. He attached them to an old coat and was able to build a display with a 160 x 120 resolution, which he notes on his blog is exactly half that of an iPod.
If you want a coat like this it will be expensive, largely due to the cost of the LEDs. For $39,995 Forbes will make you one that is a full wrap-around display; a front-only will set you back $24,995. Wait time is about four months.
