-What's Whalesong?  It's a Racket to JavaScript compiler.  Whalesong
-will be used to support World programming for the web.  It will be the
-evaluator for the upcoming versions of Moby Scheme, as well as
-WeScheme.
-
-
-We can support simple animations, as you'd expect:
-
-(Show a world program: the falling rain drops program.)
-
-
-We can do programs that have interactivity, such as:
-
-(Show another world program: pacman.)
-
-
-A core idea behind Whalesong is to reuse Racket's infrastructure as
-much as possible.  I'm not a compiler person, so I cheat, by
-piggibacking on Matthew's work.  Whalesong reuses the bytecode
-compiler, and translates the bytecode to JavaScript.
-
-I really am reusing the linguistic features of Racket.  For example,
-let's look at the less-than-impressive program output below.
-
-(Show the hello world program)
-
-
-This is trivial, right?  Let's look at the source code.
-
-(Reveal that the program was written in BF)
-
-
-Yes, this is unholy, but it works.  We really are using Racket's
-underlying language features to handle reading, macro expansion, and
-optimization.
-
-
-
-Because we're on the web, we may even want to use functions that we've
-written in Racket as a part of regular web pages.  Whalesong lets us
-do this.
-
-(Show the factorial example, and how it can be used by external
-JavaScript on a web page.)
-
-
-
-There's quite a bit that's missing: we don't yet have all of the
-primitives necessary to compile racket/base, so all Whalesong programs
-currently have to be in a language that ultimately bottoms to (planet
-dyoo/whalesong/lang/base).
-
-I'm going to get a release out in the following month, and the new
-versions of Moby Scheme for Smartphones, as well as the WeScheme
-environment, will be using the underlying evaluator of Whalesong.
-
-
-If you're interested, please talk to me during the break.  Thanks!
