Screencast on Meta Programming versus Programming Ruby

Hello David,
I see that you have expanded the meta-programming chapter significantly in the third Edition. Also, you have released a screencast as well.
My question relates to Metaprogramming – I have the third edition Beta of Programming Ruby but I have not bought the screencast. I am however, very interested in learning Meta Programming well. In what way does the screencast relate to/supplement the Metaprogramming chanpter in your book?
Regards,
Bharat

The screencast complements the material in the chapter. I feel it goes deeper in places and less deep in others—some things are best expressed in print, while others are expressed better interactively.

Just went through all the five episodes.
Well done.
An edisode or two by one of your experts on irb/rails console power use would be very useful to me.
Regards,
Bharat
