Use two fields, where one is read-write and the other read-only. The same information can be written to both fields using either a trigger or field-update rule. Display the read-only when it's closed, else display the read-write field.

Of course, that's probably easier to do in Visualforce than not.

You can add a validation rule like

AND(ISCHANGED(Field__c),ISPICKVAL(Field__c,"Close"))

That would throw an error if the field's value is "Close" and someone tries to change it.
