Since Wainwright called the similar SKOP75 6 bits I'm going to call the above p90 Silverstream after the MLPFIM character; the glider moves back and forth like a fish (or in Silverstream's case a seapony) streaming through water and the hippogriff is part of the Student Six (90 = 15 × 6).
Why do you have to call it that after a character in mlp???
I'm getting weird flashbacks.

EDIT by dvgrn: This didn't seem like an "unusual catalysis" -- there's a fairly normal block catalysis in generations 18-21, but why make everybody sort through a big messy pattern to find that? Just take the time to post the specific part of the pattern that is the actual catalysis, and maybe explain why it's unusual.

This post was annoying enough that somebody reported it, so I moved it (and added this note).

The pattern does not include an unusual catalysis at the indicated time, only two standard block catalyses, where the block that performs the second catalysis happens to have been created in the first catalysis (and it is not unusual for a block to be created naturally then perform a natural catalysis).

At generation 8 ~ 13, the rabbits catalyzes the glider and turned it into a block.

EDIT by dvgrn: This post also got reported and moved.
... off-topic because it features sparkings, not catalyses, and neither sparking a glider to make a block nor using a domino spark to add a bridge in the demonstrated manner are unusual.

Please try to make sure to understand topics a little better before adding posts to them.

After discoveries such as electricity, radio, and integrated circuits, how does only a new smallest odd-period gun imply that God is dead?
I agree. Suppose god does not exist. Then god is not dead, because they would need to exist to die.
Suppose god does exist. God is still not necessarily dead-the creator of the universe could easily add something to prevent us from killing them.
My point was that according to Christian (I don't know of any other religions that discourage human ingenuity.) belief, God did not want Adam and Eve to eat from the Tree of Knowledge (Genesis 2:17). Because Abrahamic religions believe that God is omnipotent, if God were alive, God would have prevented humans from eating from the Tree of Knowledge, so any example of human ingenuity is evidence that God must be dead. My point is that more significant and monumental discoveries would constitute more convincing evidence that God is dead.
Of course, this is stupid (because God talks later in the Bible), but I can't think of any other reason why people making discoveries could be interpreted as signifying that God is dead.
I have historically worked on conduits, but recently, I've been working on glider syntheses and investigating SnakeLife.

Genesis certainly portrays God as powerful enough to prevent people from eating from the Tree of Life (Genesis 3:22–24).

It has been proven that there are no finite patterns that appear to be Gardens of Eden in every outer-totalistic rule, for in rule B/S012345678 there is no Garden of Eden.

It has also been proven that there are no finite patterns that are not Gardens of Eden in any outer-totalistic rule, for in rule B012345678/S012345678 all finite patterns are Gardens of Eden.

By the way, here is a Garden of Eden in OCA:

Another problem in my attempt to keep the shapes as simple as possible. If a white tooth meets a blue tile as I have here, then it could also be a blue t**th meeting a white tile.
Screen Shot 2016-05-06 at 12.20.40 PM.png
This is a problem if the blue tile really only has one blue tile as a neighbor but can be placed as if it had two by touching the face of a white tile.

This is fixable by making sure the contour of a blue-white coupling is different from a blue-blue coupling, since gray tiles enforce the contours. Originally I had something like this and mistakenly believed I could simplify it away. So it's a work in progress, but I believe the basic idea is correct.

Update: I fixed the original image by making the blue teeth wider. This address the specific issue. Let me know if anyone sees other potential for tilings that aren't still lifes (explicitly ruling out the tiling by all gray squares).
Please don't post names of brands that you do not support. Thanks.
