answer: TED
context: Title: TED (conference)
  Passage: TED (Technology, Entertainment, Design) is a media organization which posts talks online for free distribution, under the slogan "ideas worth spreading".  TED was founded in February 1984 as a conference, which has been held annually since 1990.  TED's early emphasis was technology and design, consistent with its Silicon Valley origins, but it has since broadened its focus to include talks on many scientific, cultural, and academic topics.
  Title: Heather Barnett
  Passage: Heather Barnett is an English artist and university professor working in BioArt, environmental art, and food art.  She works with slime mould.  In general, her work with slime mould involves starting the mould to grow in one spot, setting a piece of food that is attractive to the slime mould some distance away (since this is a small organism, "a distance away" could only be a few inches), letting the slime mould grow toward the food, and documenting the process.  She has given a TED talk about slime mould.  She is the founder of the Slime Mould Collective, a group of scientists and artists who work with slime mould.  She was also the 2014 "Artist-in-Restaurant" at the London restaurant Pied-a-Terre.  For four years the restaurant has chosen an artist each year to spend time at the restaurant, eating and lingering in the working areas of the kitchen observing, and then to produce artworks reflecting the experience.  She has exhibited at the Victoria & Albert Museum and the Science Museum, London.
  Title: Samuel Moody Grubbs House
  Passage: The Samuel Moody Grubbs House is a historic house located at 805 E. Union Ave. in Litchfield, Illinois.  The house was built in 1873-74 for Samuel Moody Grubbs, a banker who later became Litchfield's mayor.  George Ingham Barnett, a prominent St. Louis architect, designed the Second Empire house; it is the only standing Barnett design in Illinois.  The design is typical of the second half of Barnett's career, when he shifted from Italianate to Second Empire designs, and represents a popular style in postbellum America.  A mansard roof with slate tiles tops the house; a cornice running along the roofline features paired brackets.  The front of the house features a wraparound porch supported by columns.  The house's corners have bold quoins.  In a deviation from the typical rectangular plans of Second Empire houses, Barnett gave the house a cross axis plan with projecting wings.
