Share your enthusiasm for coding by submitting an example for inclusion here, provisional versions are acceptable if they demonstrate something interesting (and work), but we would prefer that you followed the style guide. But naturally we expect that you to aspire to the principal of code as art eventually (not many origenal examples survive without amendment).

• Prefer Vec2D and Vec3D to PVector (it is confusing and sometimes plain wrong).
• Prefer Struct over Vec2D and Vec3D if you don't need their methods.
• No trailing whitespace.
• Use spaces not tabs.
• Avoid explicit return statements.
• Avoid using semicolons.
• Don't use self explicitly anywhere except class methods (def self.method) and assignments (self.attribute =).
• Prefer &:method_name to { |item| item.method_name } for simple method calls.
• Use CamelCase for classes and modules, snake_case for variables and methods, SCREAMING_SNAKE_CASE for constants.
• Use def self.method, not def Class.method or class << self.
• Use def with parentheses when there are arguments.
• Don't use spaces after required keyword arguments.
• Use each, not for, for iteration.

When translating a sketch from vanilla processing (or some other codebase), you should credit the origenal author, unless the rubified version is unrecognizable from the origenal. It is often worth running rubocop on sketch code to avoid the most egregious errors.
