### Instant Insanity (W3)

Das Puzzle-Spiel kommt ganz harmlos daher, aber man wird anscheinend "Sofort Wahnsinnig", wenn man feststellt, dass nicht so leicht ist und die "Trial and Error"-Methode eventuell nicht zum Ziel führt.

1.4 Instant Insanity

So far, our motivation for studying graph theory has largely been one of philosophy and language. Before we get too much deeper, however, it may be useful to present a nontrivial and perhaps unexpected application of graph theory; an example where graph theory helps us to do something that would be difficult or impossible to do without it.

"Instant Insanity" is the name given by Parker Brothers to their 1967 version of a puzzle which has existed since antiquity, and which has been marketed many toy and puzzle makers under a variety of names, including: "Devil's Dice" (Pressman); "DamBlocks" (Schaper); "Logi-Qubes" (Schaeffer); "Logi Cubes" (ThinkinGames); "Daffy Dots" (Reiss); "Those Blocks" (Austin); "PsykoNosis" (A to Z Ideas), and many others.

Oracle of Bacon

Shortest Path between Pairs of Actors

About the Oracle of Bacon

This is the most comprehensive version of the Kevin Bacon game on the web. The object of the game is to start with any actor or actress who has been in a movie and connect them to Kevin Bacon in the smallest number of links possible. Two people are linked if they've been in a movie together. We do not consider links through television shows, made-for-tv movies, writers, producers, directors, etc. For example, you might wonder how Mary Pickford can be connected to Kevin Bacon. One answer is that:

Mary Pickford was in Coquette (1929) with Louise Beavers was in All the Fine Young Cannibals (1960) with Robert Wagner (I) was in Wild Things (1998) with Kevin Bacon

Then we can count how many links were necessary and assign the actor or actress a Bacon number. Bacon numbers higher than 4 are very rare. In the example above, Mary Pickford has a Bacon number of 3. The Oracle uses the data from the Internet Movie Database and can give you the shortest path from every actor and actress that can be connected to Kevin Bacon.
