For example here is a way to produce an unusual still life with 5 blocks:

`x = 21, y = 27, rule = LifeHistory`

It would take a lot of synchronized gliders to produce the same result.

Blockic seeds for LWSS, MWSS, and HWSS are scattered about in other topics, so I have collected the best ones here:

As far as I know it takes at least 5 blocks to produce a clean spaceship, but 4 blocks seems possible.

It may take extra blocks to do cleanup:

aircraft carrier:

`x = 84, y = 28, rule = B3/S23`

pulsar with cleanup the hard way:

`x = 29, y = 36, rule = LifeHistory`

pulsar without cleanup the easy way:

`x = 25, y = 21, rule = LifeHistory`

It is desirable to minimize the number of blocks needed, as with the pulsar.

8-block paperclip:

`x = 29, y = 30, rule = LifeHistory`

3-block glider shift to a different lane:

`x = 20, y = 24, rule = LifeHistory`

5-block glider shift by a half-track:

`x = 29, y = 24, rule = LifeHistory`

2A!

Post any interesting Blockic seeds or improvements in this thread.

Blockic seeds that result in multiple gliders should be posted in the Blockic Splitters thread.

EDIT:

Blockic seeds are better if the blocks are not too close to each other. That way the seed itself is more easily constructed. Two empty cells between blocks is good. The Seeds of Destruction program does this for you.
