If you are tired of the Batman Light-Up T-Shirt that we covered here at GeekAlerts last year, here is something new to light up the day for you and the people around you.

This cool light-up t-shirt features four different emoticons that you can choose to illuminate depending on your mood or the message you wish to convey.

You can show a happy face, a sad face, a winking face or a surprised face, depending on how you feel. A glow in the dark/UV reactive screen print completes the effect.

The Illuminated Emoticon T-Shirt requires 4xAAA batteries. The product goes on sale on the 20th of November 2009 with a recommended retail price of £29.99 (about $48).

Designer Jaehyung Hong has come up with yet another useful product idea.

The subtle “Wire Button” is attached to the button of your shirt and will take care of any annoying tangling headphone cords from your MP3 player.

More pictures and info about the Wire Button over at Yanko Design.

Reader comment: Jaehyung Hong,
