Algodoo

I started off with something similar to Raramalum's antigravity machine, and went on a quest to make something that would generate lift by being moved horizontally. This version is still a little buggy, but it begins to lift its own weight around 70 m/s. Improvements in this concept could create a whole new generation of flying machines.

UPDATE: Now uses both positive and negative air friction to produce more lift with less drag! Lifts its own weight at 40 m/s now!
