If you find Dasher hard to imagine based on these static pictures, please take a look at the movies below. When you watch someone else steering Dasher, you may find it looks difficult, but be assured: it is actually very easy; it's a lot like driving a car.

You can try Dasher right now, in your browser, if your browser is Java-enabled.
