"When I guide youngsters on Scratch programming and write posts to analyse some well-designed Scratch projects, I realize that there are not many book choices focusing on advanced Scratch programming in the market. Most of the Scratch coding books offer step-by-step instruction which is generally suitable for beginners or intermediate level learners.This book is written to support those who would like to touch the high ceiling of Scratch programming and to understand how to develop challenging projects on Scratch. I will concentrate on the use of List, Clone and Pen functionalities by analyzing a few sample projects in depth. Through combining those features artfully, we could realize some amazing functionalities."
