about halfway through this book and I was hoping the new revision would fix a lot of the code errors, so I put it on preorder. But alas, even this revision has terribly large amount of errors in it (mostly openFrameworks, some processing), making some of the code unusable or esoteric (sometimes entire sections of code are missing). There a ton of mislabeled pictures, some are even missing? so you get references to pictures that don't exist. HOWEVER, Few redeeming qualities are that it has great info in it aside from all the code errors, you can tell a lot of hard work went into it. I would suggest oF website and other tutorials alongside this book if you want to learn to actually code this stuff, they unfortunately have helped a lot more, since the code is usually correct.
Would be nice if it just worked, but with coding constantly updating I can see how this would be a headache, so I don't blame author, some errors are clearly publisher too. If you can tollerate errors in code or missing code, then this really is a well put together book. The interviews are great and with prominent designers, so those alone are almost worth it. It gives you a great outline of what you can do with all these languages and great examples of what is possible (even if it doesn't always work :) Would still recommend this book, just be ready to be patient.
