I've written an ugly Scheme to Befunge compiler.

This page holds it:

This is awesome! And hilarious!

Would you recommend Appel's 'Compiling with Continuations' to learn about converting to CPS?

Great work!

Thanks!

On learning CPS, it really took me a lot of
different readings to understand how it works.
Probably the most helpful was Queinnec's book
LiSP (Lisp in Small Pieces).

After lots of time thinking I finally got CPS,
it always lends itself to new forms of understanding.

Unless you are Guy Steele ;)
