This crawler consists of Herschels climbing up gliders. A single Herschel on a (27,1)c/72 glider stream leaves a trail of debris behind, but it is possible to combine (27,1)c/72 Herschel climbers into pairs, triplets, etc. to produce clean climbing reactions, rakes, puffers, and so on.

Work was done on making a spaceship around this reaction in 2016, but it seems to have been mostly forgotten.
