Algodoo

A tilt-controlled segway (just like the real thing).
Controls: move the center of mass by pressing left & right arrows.

An indicator led in the handle will start blinking yellow if you go too fast, and the device will actively resist any further acceleration, but if you insist, it'll turn red immediately before the loss of stabilization.
Let's see if you can make it through the obstacle course. Try to land upright after the last huge trampoline (Tip: enter the ramp at maximum speed)

DISCLAIMER: The scene is a joke, not intended to offend any women or anyone sensitive to explicit bodily dynamics
