A partial color changing reflector. The sacrificial boat here has to be replaced with either a permanent catalyst or a transparent object restored by other catalysts for the reflector to work. This would act as a stable version of a bouncer. If completed, the reflector would have a repeat time of 47. It is fairly simple, so it might be already known.

No clue if one extendible in two directions exists, but finding this one was frustrating enough.

[Empty Emptiness]

I'm not sure if the gliders come from infinity. How might I verify this?

Maybe just use shift.py to move each glider 10 ticks diagonally in the appropriate direction, and see if you still get the same final pattern. In point of fact, you don't:

Code: Select all

x = 15, y = 33, rule = B3/S238
13bo$12bo$12b3o3$2bobo$3b2o$3bo16$8b3o$8bo$9bo5$3o$2bo$bo!

So you'd have add a kickback and turn this into a five-glider construction.

I was very surprised to see so many pulsars in the final output, by the way -- until the extra "8" in the rule string caught my eye!

My glider-rewinder script might work, too -- as you step backwards there will come a point when the script refuses to rewind one of the gliders. I've been threatening to get back to write a version that rewinds to N ticks but throws up a warning message if some objects can't be rewound. It wouldn't be terribly difficult, but it seems I haven't found the time yet...!

EightLife generates a lot of pulsars. many of these pulsars got destroyed.

This is actually an extendible strictly volatile oscillator. The wiki page on volatility says that phonieces and self-constructing circuitry are the only infinite families of strictly volatile oscillator. That needs updated.
Speedydelete just found p30 family of extendible strictly volatile oscillator!

I just found this works also.
So maybe the wiki page is just out of date.
