The image below shows the state
of the Dasher interface
while the user is writing the word
`objection'; alternative words that could easily be written
at this point include `objective', `objects_', and `object_oriented'.
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.
When you try Dasher for the first time,
please read the tips for novices.

[In this movie, David hits the space bar to start the program
going, and after that he uses nothing but eyes; he's using Dasher version 1.6. In Dasher versions 3 and 4, we can start and stop Dasher without cheating in this way.]
