It's been known for a while that speeds slower than c cannot exist with the grain, and Macbi more-or-less said it in his post also. :P

@kiho park: I ran several searches, starting from the minimally spaced double long barge. I think all up they ran for several hours. the smallest signal was actually found on a track laid down by a signal/fuse running on the minimally spaced track.

There has been mention of signals in with the grain zebra stripes only being allowed at c, by Sokwe in the Agar crawlers thread, for example, and other places as well I'm sure. It's unfortunate these things tend to get lost and you hadn't come across it before rediscovering it.

@dvgrn: nice glider output from the signal (it is kind of like a trolley on tram tracks, but the wrong shape to take on that name I reckon). I don't expect to see it synthesized any time soon, but who knows?

Here' is a c/3 signal on a single long barge. It's the shortest at this width. There may be narrower signals, but much longer, and there's almost certainly shorter but wider signals. There's certainly nothing fairly small though.

x = 60, y = 60, rule = B3/S23:T60,60
