That picture could be of an entire region, with the power to generate millions of regional forms, with an infinite variety in the detail. This website activates the network and allows you to collect together the relevant patterns. To understand the full reasoning and to obtain the full detail for each of the patterns, you need to see the book A Pattern Language . Scan down the list, and find the pattern which best describes the overall scope of the project. Notice the other patterns mentioned.
Asterisks indicate the degree of confirming evidence for the pattern.
No asterisks - no confirmation. Tick all of the Low Order Patterns unless you have some special reason for not including them. Ignore all the High Order Patterns unless you have the power to create these larger patterns. Now your list has more ticks. Turn to each pattern and now tick only relevant Low Order Patterns.
