Hong Kong inventor Keikko Lee (shown in photo) designed a thin light that runs on solar power. Similar to a post-it note, the light sticks to the window during the day for solar charging and then can be moved to stick onto anything else for ambient lighting...

The sticker would have electroluminescent material on one side and solar panels on the other. Would you use the product?
