Some links to discussion about 10 PRINT CHR$(205.5+RND(1)); : GOTO 10. One of the common ways to interact with the idea seems to be writing and posting re-implementations of the program in other languages and environments.

Geeta Dayal's review of the book in Slate.

Discussion on Reddit r/Programming, including a hilarious Enterprise Java version.

A discussion at Stack Overflow stemming from a Bash shell version posting.

A discussion on Hacker News, which also features a number of re-implementations.

A post on Boing Boing, which also includes a good comment thread.

Casey Reas posted photos of the book that show you how gorgeous it is in person. In addition to co-authoring the text, Casey designed the book itself.

The book is currently out of stock at Amazon, but I wouldn't believe the 2-4 week shipping time (I bet they'll have more next week), but in the meantime, Barnes & Noble has the book in stock for the same price ($19). So you can still put 10 PRINT under the tree...
