G-to-LWSS is a glider-to-LWSS converter. It may refer to the specific converter shown in the infobox at right, constructed by Chris Cain in October 2015. Its recovery time is 78 ticks, matching the recovery time of the syringe.[1]

Many other composite G-to-LWSS converters have been constructed. The first G-to-LWSS was constructed by Paul Callahan on May 17, 1997. Stephen Silver constructed a smaller version, using the same glider/Herschel/block interaction shown at right, on September 24, 1997.

A different reaction, which directly produces an LWSS at the expense of a block, was used by Chris Cain in May 2015 to produce a direct Pi heptomino-to-LWSS converter.[2] This PS12T565L pi-to-LWSS conduit can be attached to a standard Herschel-to-Pi and syringe to yield a relatively small G-to-LWSS; however, it has a much larger recovery time than the converter in the infobox.
