Design By Numbers is a book and companion language by John Maeda. I read the book, but couldn't find an implementation of the language anywhere, so decided to implement it myself.

Currently, the supported statements are

• Line
• Paper
• Pen
• Set
• Repeat
• Command

(that's everything through chapter 12 except Load)

try python dbn.py -f tests_dbns/square.dbn to see an example
