[Hackathon] Hac phi roundup

[Brent Yorgey]

Hi everyone!

Thanks to all who attended Hac phi and made it such a success!  I hope
everyone had a great time writing code and meeting other Haskell
hackers--I know I did.

I'm planning to write a little round-up post on my blog and I'd love
to include short descriptions of what projects people worked on.  I
remember what some people worked on but not everyone.  So if you'd be
so kind as to send me a one- or two-sentence description of what you
worked on while at Hac phi, I'd very much appreciate it.  Also, please
send along any links to blog posts, pictures, etc. which I can include
as well.

thanks!
