Version: 1.13.8 Add a widget to help your readers build custom queries using drop downs of your categories and custom taxonomies. The latest version
Taxonomy Picker is a widget which you can include in your sidebar to help visitors build complex queries using categories and your custom taxonomies by chosing terms from drop down boxes. The widget also includes a text search making it easy to search for text only within certain categories or taxonomies. The latest version of the enhanced widget includes support multi-select combo boxes and Post Type.

Of course some people prefer to regsiter their own custom taxonomies in code and that is fine.

You can display the query the reader selected from within code by using echo tpicker_query_string();
