[racket] Live coding screencasts

Hi all,

I am relatively new to Scheme (and Racket) although I have been playing
with Clojure for a while. I am having a little bit of trouble in
getting started with the programming workflow. I don't mean "tools" (I
am using Geiser in Emacs and it's great!), but rather the way of
thinking about solving problems in an idiomatic scheme way.

I am a fan of the video lectures of SICP
(http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-001-structure-and-interpretation-of-computer-programs-spring-2005/video-lectures/).

I find that seeing someone else explaining how to program is much better
than reading a book, although I like to spend time reading someone
else's code.

I have recently been following the screencasts by Daniel Silverstone
(http://www.youtube.com/user/KimballKinnison/videos?view=0) where he
solves some project Euler problems in Haskell and I found them very
interesting and useful to grasp the way of thinking.

Are you aware of similar lectures/videos/screencasts using Racket or more generally Scheme?

I already asked this question on the Guile users list, and I was suggested to have a look at 
Andy Wingo's lecture at fscon 2011 which is great:

Thank you.
