OLPC computers (those little green XO1 laptops you have perhaps seen Tony Forster or myself lugging around) includes Alan Kay's Smalltalk / Squeak / eToys environment, built around Python. You can tinker with this using Sugar on a Stick.
From my observations of his contributions to the OLPC project, Alan is always emphasizing that computing not as an end in itself, but as a vehicle for learning how to learn. The computer revolution is yet to really start happening.
"Points of View - a tribute to Alan Kay" is a collection of previously-unpublished essays written to celebrate Alan Kay's 70th birthday. Twenty-nine luminaries from diverse disciplines contributed original material for this book.
From the IAEP mailing list I read that supplies of the first printing of the book were depleted less than six hours after the announcement. A second book printing is available in return for a small and worthy charity donation. A copy of the entire book in PDF is available for download, for free, from the following page.
Important stuff for ICT educators, check out the book. :-)
