My book review of the Official Scratch Jr Book, from No Starch Press. This is an excellent book. View the book review in HD, if you are able to. I recorded it in 2560 x 1440 pixel format on a 27-inch iMac. I used a Logitech Pro 9000 webcam and Screenflow 5, from Telestream. The scanned pages from the book were presented using LibreOffice Presentation program.
