Pipsquirter 2 is a period 7 pipsquirter discovered by Noam Elkies in August, 1999.[1] Because of its easily-accessible domino spark, it is useful in the construction of larger patterns such as the p49 glider shuttle, the first known period 49 oscillator.
As a reflector
Pipsquirter 2 is most useful because of its ability to act as a 90-degree glider reflector (see p7 bouncer) when it is combined with a block, boat and eater 1. It takes 9 generations to recover from the impact, and the input path (in green) and output path (in red) of the glider are shown below. This reaction is the basis of the p49 glider shuttle and the bricklayer.
A version of the pipsquirter stator with slightly higher clearance is shown in the p7 bouncer article. The following larger period-7 pipsquirter reflector is used in cases where space is limited where the reflector should extend southward for as short a distance as possible.
A different version lead to a period 56 gun due to its thin size.
