The hardest model

[Lephantome92]

where are diagrams for previous ryu zin's?

there are no diagrams for any ryuzin and I think that attack of the kracken is the hardest model.

[zxop9]

is there a cp or diagrams for attack of the cracken, or any of brians chans models? i went to his site and i guess he sells the models he folded but can you get diagrams for them and fold them yourself instead?

I saw the crease pattern on flickr one night

Search around on his site. Look at a lot of his models. Some have CPs, some don't. I believe there are even a couple diagrams (I think just for his leaf and something else simple), but there are CPs to be found. You might try searching online, too. CPs for several of his models were displayed at the OUSA 2007 convention (Nekobus, etc.).

I've found it here http://www.flickr.com/photos/mointrigue/1717197468/

Also, check Brian's Flickr page. There are some CPs there that aren't on his webpage.

that's what is frustrating me so much, i have once made one, and the next day i just couldn't do it. when i try i can do the first 2 twists, and the third one is exactly the same, but i just doesn't work. ah well, got to try again some day.

the same things happened to me. i did a step in an impossible model i could never do..once..but the paper was too small so i had to throw it away..i tried 10 mins later...Guess what? I can't do it

i had tried spring into action, but i was stucked in the middle..

I've done the Spring into Action. It's really boring to fold though. I never tried the red sea urchin. I saw the 145-spined purple one and made it instead. It's not hard at all.

For me it's Marc Kirschenbaum's one-piece Chessboard. I've never gotten a satisfactory one. I'm not sure it's possible.

Jared, that chessboard brings back terrible memories. I said, "Oh this will be fun". I was horribly wrong. I have seen pictures online of it though. It has a nice end result, but I will never try it again. I have better things to do like put my hand in a blender.

Bethnor, the praying mantis takes a lot of practice. It was difficult for me at first, but now I have three with minutely ripped antennae.

I tried one those sea urchins on a road trip once. Don't worry I was not driving. I think it ended somewhere between this is taking too long and oh my gosh I ripped it.

I think satoshi kamiyas wasp 2.0 is pretty damn difficult, I still can't fold it, if anybody can help me it would be much appreciated, /

[chesslo]

the hardest one for me is the kamiya housemaid, just looking at it gives you an headache

[gordigami]

For me , the hardest model is always that one that I really look forward to completing, but has that one seemingly impossible fold, thereby quelching completion.
The key, of course, is to never give up . Oftentimes, the solution seems to be directly proportional to the amount of rest that one has gotten.

[pereze]

I agree gordigami. And with that, I think that Phoenix 3.5 is a very difficult model to complete in a way that compares to Kamiya's folding. Of course, it isn't necessary to finish it off like Kamiya...

Mark Kirschenbaum designs are extremely difficult. I have folded one of his designs satisfactorily, the teddy bear, but everything else is way too difficult for me to wrap my head around. The crabs, chessboard, and biplane always turn out way too crumpled up for me to even complete. I personally have no idea how he even folds it himself.
