Check out Gear Tie from Nite Ize. They're reusable twist ties. Brilliant, right? They're not new, but I saw them for the first time at CES. They come in various sizes from the short one on the right below that's 3-inches long to 64-inch bad boys for zipping up whatever the heck you want. Use them for instrument cables, power cords, cables for your Mac, rope, watering hoses, or whatever, only with Gear Tie, you can reuse them. They start at $4.99.
