LOGO challenge - blob

Working with recursion. What is going on how does each iteration feen into the next? All within a geometric setting.

Problem



Think carefully about the procedure below. 

This procedure looks at the technique called recursion and can be used to build up a particularly pleasing catalogue of patterns that spiral!

Investigate this intriguing procedure, try to formulate some ideas about what is happening and test any conjectures that arise.

TO BLOB :A :C 

FD 5 RT :A 

WAIT 10 

BLOB :A + :C :C 

END

You will have to tell LOGO to "HALT" at some point otherwise this will go on forever - why? 

Try: BLOB 3 9 / BLOB 2 8 and go from there. 

BLOB 1 10 and BLOB 11 18 are reproduced here for you...
