Four L-System and one IFS. L-System has the limitation on the length of the lists for possible work in Scratch. Still, this is slow online. I did this project to relax my head on the difficulties in another project that I want to do, where I need to learn to "compress" lists for faster, like the procedure created by mathjp, which He describes in http://scratch.mit.edu/projects/mathjp/1477506 Sounds from Scratch (Music loops) (I like ex.5 and ex.1)
