Ever wish you had the help of a magic wand to deliver that key sales presentation? The FinRing is a colorful, cat-eye-shaped device that, when attached to your fingertip, serves as a fully functional mouse, allowing you to wirelessly navigate your onscreen cursor by simply gesturing with your hand and double-clicking with your thumb. You'll never have to hunch over a keyboard during a presentation again. Plus, because the FinRing has no moving parts, there's nothing to clean. All you need is an available USB port.
