+### Code
+A Clock class is created, with two instance method, one
+for setting purposes (in this case to set the name of the clock),
+and the `widgets` method, which holds the actual business logic.
+This method uses a nested method that is responsible for
+setting the current time and start counting from it.\
+The Clock will have a random color.
