A game invented in October 2009 at First Flight High School where participants use the word appletart or some of its variants. Originally it was focused on who could say it the loudest but has evolved over time. The ways to play include: 1. Who can say appletart the loudest? 2. Who can say appletart the most in a game? 3. Who will say appletart last? 4. Who will day appletart in the funniest or most awkward situations? 5. What word will be matched when someone says appletart? Will it be appletart, applepie, poptart, or something else?1. kid 1: Appletart. kid 2: Appletart! kid 1: APPLETART!

An '''inline inverter''' is a reaction with the Gosper glider gun in which it eats an incoming [[glider]] and thus can be used to invert the presence or absence of gliders in a [[period]] 30 stream, with the output glider stream being in the same direction as the input glider stream.<ref>{{cite web|url=http://www.argentum.freeserve.co.uk/lex_i.htm#inlineinverter |title=Inline inverter |work=The Life Lexicon |publisher=Stephen Silver|accessdate=May 22, 2009}}</ref>

The Gosper glider gun is the first known gun, and indeed the first known finite pattern with unbounded growth, found by Bill Gosper in November 1970. It consists of two queen bee shuttles stabilized by two blocks. It is the smallest known gun, and, as it can be constructed using only eight gliders, it has the smallest known glider synthesis of any gun. It can be destroyed completely by five gliders, as shown below.

Inline inverter

An inline inverter is a reaction with the Gosper glider gun in which it eats an incoming glider and thus can be used to invert the presence or absence of gliders in a period 30 stream, with the output glider stream being in the same direction as the input glider stream.[1]
