LED Light Drawing Pens

Doodle ephemeral drawings with LED Pens!
One day I realised I can’t stop doodling while talking on the phone or sitting on a boring lecture. I doodle stories or just simple element of nature. I usually put my ‘pieces of art’ into the rubbish bin. But how about wasting less paper and still creating small pictures?

After LED Hula Hoop idea with which you can enchant your friends with hip movement. I stumbled upon another illuminating project of LED Light Drawing Pens on Instructables. I was flabbergasted at what can be done with a few rays of light and simple digital camera. When I created my own show, my children were dazed by the beauty of colourful lights and even more stunned when they saw photos of the stories I doodled for them.
