The use of white LED matrix in a cotton napkin, powered by a small removeable battery.
Imagine that romantic evening, bottle of wine ( or non alcoholic cocktail..for those who cant handle), music and a mood changing LED napkin in your candlelit room. The LED lights will be affected by the mood you are in, and like me are touch sensitive.

Also, Great for Valentines day in your favourite restaurant or any special occasion. If the restaurant is poorly lit then take the napkin with you to help you on your way. If you go onto a club, take it with you and watch as people see you light up the dance floor to that Rick Astley song.

For those with a balcony, what better, than an evening with drinks, luxury burger dinner, and the gentle glow of your Emotional Napkin illuminating your table ( or leg) as you relax with your loved one, sharing a copy of the National Trust times, before moving into the lounge to catch up with the latest episode of Heroes.

Perfect and commercially viable !!
