Interesting banana spark to beehive (The banana spark can be supplied in two directions):

Code: Select all

snip

If you replace the eater1 with an eater2 and add a block, you almost get a p21 oscillator:

Code: Select all

x = 17, y = 12, rule = B3/S23

bo$3bobo$4bo!
[[ STOP 18 ]]

That implies that the combination of the beehive, two blocks and eater 2 has some niche uses as a catalyst, as a 'beehive spin', if you will:

Code: Select all

x = 17, y = 15, rule = B3/S23

It can destroy a long hook with tail:

EDIT: As a matter of fact, this catalyst is equivalent to the loaf spin reaction in Baker's dozen, but is much cheaper and has higher clearance, at the cost of a higher recovery time:

Code: Select all

I don't know what you mean by monomerizing the Unix, apart from along the diagonal axis, but these recover in 12 generations, so I don't think that would be practical even if you were to successfully come up with a half-unix partial.

yes, that catalysis can also be done with an eater2 or block

in general, if you want to combine an eater1 and a block catalysis like so, then you can replace it with an eater2 (as long as the eater2's catalysis creates a b2o$o2bo$o! when used on a block)
