Hack on!
I did a little presentation on Hy at Pycon Canada earlier this year [1].
Hy has come a ways since then even. Shortly after that talk we added succinct syntax aliases for QUOTE and QUASIQUOTE. And we added a nice clojure-inspired core library.
It's a cool little language. Fun to hack on. You could learn a few things if you do. And I do hope that we can start help creating documentation for the Python AST module via this project.

A+ for presentation
So it just desugars into Python? I see there is a section in the documentation for macros, but there's nothing there. Does it support AST macros right now? I thought of doing something similar to this except doing some kind of static or gradual typing (that would be a larger project though).
Very nice. Surface syntax (and some semantics like interop) seem to be heavily inspired by Clojure :-)
Hy is neat. I love Lisps that "compile" or are embedable within host scripting languages.
My favourite one to hack on (owing to my PHP ability) is Pharen[0]. Very neat little Lisp that compiles down to PHP, which is very fun to play with. I highly suggest giving Hy a go if you're a Pythonista, as you can learn a lot about programming in general by seeing how these sorts of languages map to the host. Very fun to hack on, too!
To quote Dark Helmet, "What the hell am I looking at?"
Not bad. Could be a very useful tool to teach Python programmers Lisp, although I don't think Python benefits much from converting its syntax to sexprs.

=>Heh, recognized reverse polish notation right away. One of the companies I interviewed at last year had me program an RPN calculator fed by CSV spreadsheets. Weirdest thing I've made to date by a pretty wide margin.
Incredible implementation.
What blew my mind is this actually worked on my iPod Touch and brought up the keyboard. Usually "dynamic" JavaScript keyboards or games totally fail on there..
Excellent. I thought what a LISP on top of the Python runtime would be (like Clojure + JVM), didn't knew this existed already.
"(defun f x (x))" gives a Python stack trace.
Finally my knowledge of Scheme comes in handy!
Love at first sight with the presentation
I think this is fucking amazing.
effin' finally. now to do some serious lisping!
where's cons?
(-40 1) = 40.
To be honest this is a stupid syntax. Basically it reads 40 - 1 from what I can tell from playing around. Why would you take -40, something that everyone understands as negative forty and make it mean forty minus?
This could be the next big thing.
Is Python really that awesome?
[]+1 = [] 1
[]+[] -> error ...
It's a dialect of LISP that's compiled down to Python AST IICR.
