Here's one for retro gaming geeks. It's another item in the huge range of Nintendo inspired goods (including pillow cases and wallets) that are available: a Nintendo NES controller card holder with all the buttons of the original controller. It also has two compartments, one for your business cards and the other for the cards you collect. However, if you want to be taken seriously at work, it's arguable how much pulling a card out of this thing will help.
Perhaps unsurprisingly this marriage of gaming and business has come out of Japan. It's not on sale until October, but is available to pre-order for 21.46 Euros.
