Algodoo

Prototype. Highly experimental equipment. Electromagnetically activated parachute, tested in simulated conditions. Nanoparticle-based, drag-inducing, expanding material, framework stiffened with lightweight carbon nanotube springs. Handle with care, contents under high pressure. Still being worked upon. Use F to activate. Somewhat impractical, uneconomic and dangerous, but slows down amazingly fast.

Version 1.7: Added altimeter with landing speed display for additional impracticality and uneconomic-ness. But for the few hours/minutes/seconds/milliseconds you'll be falling, it'll be "awesome and easy to use"™.
