Does the world really need Post-it 2.0? Ask those of us with Post-its habitually plastered on our monitors, walls, backs, and foreheads, and we'd probably be hard-pressed to come up with suggestions for improving the classic attachable notes.
Still, the designers at Sequoia Studio have come up with an inventive concept product called E-notes. The notes use tactile and flexible electronic paper technology and are powered by a solar captor. They can be stuck and unstuck to surfaces easily using a glue inspired by the adhesive that keeps the gravity-defying gecko in place. The best part? They can be reused, thus saving paper.
E-notes even have a visual alarm/organizing function that changes colors. That we like.
