http://en.wikipedia.org/wiki/Fractal

"Fractals are typically self-similar patterns, where self-similar means they are "the same from near as from far" Fractals may be exactly the same at every scale, or as illustrated in Figure 1, they may be nearly the same at different scales. The definition of fractal goes beyond self-similarity per se to exclude trivial self-similarity and include the idea of a detailed pattern repeating itself."

And watch this: http://www.youtube.com/watch?v=G_GBwuYuOOs
You will notice that the same patterns appear again and again

I'm also able to replicate the effect in modified designs of the OP one: http://www.fantasticcontraption.com/?designId=11775181

Delete one of the wood rods, and it "works" (not really, it completely misses the general area of the goal)

However, i suspect the patterns of these would be different than those I have found.

Edit: Aaaand... 0-29 is done

it only succeeds up to 6, then it fails and wood, water, or wheels all have the same outcome...
also, i got conflicting numbers thru 3 test samples:

went from 1 - 22 wood rods adding 1 at a time above the imaginary line and no wood rods below the imaginary line...
recorded which designs and # of rods passed and which designs and # of rods failed...
all 3 times i did this, the passes and fails were different with the only common # being 2 rods failed in all 3 tests...
also, i tried 1 test starting with 22 wood rods above the imaginary line and no wood rods below the imaginary line removing
one at a time and got the same outcome as the 3rd test...have no idea why different results or why this glitch exists...

Yea jdc, that was my old hypothesis, back before I did the graph.

Also, I am unsure if having the wood rods attached to each other affects the results. Is it possible you might have done that?
Edit: I've tested it a bit, and it seems that connecting the wood rods has no effect on the results. So there must be some other reason your data is variate. Hmm... mac or pc?

### Re: ???

pc..i did connect the rods...also, did some experimenting with rod orientation...try 8 connected rods
horizontal above..fail?...try 8 con above and below..fail?..now try 8 con vertical bisecting the imaginary line..pass?
if all 3 are true for you, then i don't think it's my system that gave me erroneous results...it could my error...will try
again in the morning...but this is a cool mystery and i like what you've done so far!

No, I have a pc as well, and theres no evidence that 7/vista makes a difference. So I guess that idea is struck down

Hmm... I might have an explanation for the bisecting rods. Perhaps a rod that exists in both top and bottom counts as 1/2 top, 1/2 bottom? I'm gonna test that against my graph, see what might be up

Edit: After about 12 spotchecks, it seems to be a remarkably accurate prediction. Also, having 1/2 values for this allows us to have 2x better resolution. :D

Edit2: Not really for the 2x resolution, since we can never have just half, so we cant have, say, 2 rods in the top, and 1/2 rod in the bottom.

rainbay-
this one probably has to do with the over-lapping of the static/dynamic (drag) and the
penetration of the dynamic into the water rod. the dynamic and rod are trying to separate,
but held back loosely by the tightness until enough "energy" builds up to overcome the
drag...kinda like the energy discharged when a wound spring is released...anyway, that's
my guess

zhyrek - cool!...gotta run for the time being, but i look forward to what you find out

### Re: ???

Actually, the graph seems to be isometrically patterned, and the addition of adding a half to both sides allows me to restructure the graph to BE isometric.

That's what Im doing next

### Re: ???

hey zhyrek-

i think i have enough data to predict passes and failures ie. how many rods above or below
to produce a pass or fail...
i did 2 tests to collect data but found a pattern:
1st test with 1 rod above and 1-51 rods below
2nd test with 2 rods above and 1-52 rods below

with this data i was able to predict let's say a (3,9) as a fail or a (4,23) as a fail or a (5,36) as a pass, etc.
if you want the data, i can pm you with it

I would very much like the data, and if it's not too much to ask, a few example designs showing how you placed the wood rods.
I'd like to compare it with my own data :D

### Re: ???

So I was wondering... Did anyone figure anything else out with this glitch? It is a very cool and mysterious topic, I am just curious whether or not Zhyrek ever did anything with Foss' data.

### Re: ???

He sent me the data, which I confirmed to be the same as mine (with one exception, turned out to just have been a data point put down wrong whoops!)

Looking at this with new eyes: When I said that rods that are half top half bottom count as 1/2 and 1/2 for the graph, it leads me to believe that this glitch is sensitive to the number of JOINTS on top/bottom. Regular rods give 2 on either the top or bottom. bisecting rods give 1 top, 1 bottom.

Edit: this thing I just said has no way of being tested, since its impossible to make a rod with less/more than two joints

### Re: ???

Wow, that certainly gives a new perspective to this glitch. Also, when I was looking through my levels on my "Old" level set, on this level I noticed that the small dynamic squares on the right are also affected by this glitch. When played without any contraption, they all fall down, but on certain saved designs for that level they get stuck. Apparently, it is not just contraptions that are affected by this, but dynamic pieces too.

Edit: Although that theory is untestable, it does seem quite plausible.

Edit: And on the dynamic glitch, it is not a simple pass/fail like the contraption one, but with each piece you add the squares fall in a slightly different way

That level is astoundingly weird:
0 rods: All pieces fall, except one block that gets caught on one of the small green pieces
1-2 rods: Stuck
3 rods: Every piece falls, even the one that previously got stuck

More than two modes wat

Edit: My old data vanished when I borked old computer, but I did finish about 40% of the isometric data again. Maybe I'll try to finish that in a few days

Aaaaagh this is a lot more complex than I thought it was... It is 3am here and I should probably get to bed. Maybe some realization will come to me when I'm not half asleep, but this is some crazy stuff...

Edit: Ok, that would be great. I am really interested in this glitch for some reason haha

If joints are the key, then wheels (and goal blocks) provide 5 joints which can be arranged as (5,0), (4,1), (3,2)*, (2,3)*, (1,4), and (0,5). This won't provide single-joint granularity at (0,0), but it should prove more than sufficient to test your hypothesis.

* these combinations require using rectangular goal blocks or rotating wheels with FCML

Yeah I tested those and it seems like they don't follow my joint hypothesis if those 5 joints count

However, the wheels do act as if only the top/bottom joints count: fully top or bottom acts as 2 joints top/bottom, while in the middle acts as 1 top 1 bottom

What about a pin? Could those possibly act as one joint?

Tried it, pretty sure it still has two joints, the two joints are just at the same point
