Stretch shelves by Pete Oyler made of cast rubber and machined aluminum is like a giant rubberband functioning as shelves too. Depending on your moods and preferences, you can stretch these shelves and accommodate your day to day stuff. Unlike any other this rubberband comes with a twist and an extra stretch. If all shelves used at the same time in different shapes this can be a very effective pattern wall art also and that too a bit interactive. In addition, if you are little angry you may even stretch it to release your pent-up energies.
