If you are an extensive user of Post-It, you may find this interesting. Sequoia Studio has a conceptual project called E-Note, which is kind of a futuristic version of today’s Post-It. E-Note will use a flexible electronic paper technology which will be powered by a solar captor. It can be stuck and unstuck anywhere using a special ‘Gecko’ glue. And if you are thinking is that all? Wait till I tell you that E-Note will even have a visual alarm/reminder function which it can achieve by changing it’s color (any of the 8 colors) ! Now that’s what I call “ultra-cool!”.
