Reasonator (found here) is a Tool Labs (previously Toolserver) tool by Magnus Manske which can display a prettified and extended version of Wikidata items. The tool works for all items, but has special functionality for items about people, locations, species. It also has a search function.
The tool can also show related data (from other items) through simple reasoning (e.g., for people, relatives, books authored, music composed).
