One of the goals of this blog is to provide free pdf files I've written that discuss and explain the mathematics and programming techniques I used in my projects uploaded to Scratch.
Three of these files are now available.
File: Lindenmayer Systems in Scratch
File: Koch Snowflake in Scratch
File: The Sine Function in Scratch
Simply send an email request to firstname.lastname@example.org and I will email you any or all of the above files.
The files are free of any copyright restrictions.
The links to the Scratch projects uploaded to the Scratch web site are also given.
