Speed tunnel/Snippet

The speed tunnel is a stable glider-to-Herschel converter discovered by Tanner Jacobi on July 24, 2022. It is composed of a transparent block, an eater 1, a bait loaf, an eater bridge eater, an unnamed 19-cell catalyst, and a beehive push catalyst. The glider-loaf collision would make a block on its own, but it is perturbed and turns into a pi-heptomino, then becoming a B-heptomino while restoring the bait loaf, finally yielding a Herschel and restoring the transparent block. In the pattern shown in the infobox, a ghost Herschel marks the output location.

Its repeat time is 61 ticks due to a spark from the beehive push reaction. To prevent interference of the output's first natural glider at a separation of 61 or 62 ticks, a variant of tub-with-tail eater can be used to replace half of the eater bridge eater.

The low repeat time makes speed tunnel a faster alternative to the syringe, which has a repeat time of 78 ticks and overclock periods of 74 and 75.
