Looking for a 12-part origami

[MIB4u]

Hi there! My name is Martin and I can't remember a certain 12-part origami. every square of paper is folded the same, at last they're joined together to form a sort of spiked ball... and if you only take 6 of those pieces, you can make a cube. even only 3 is possible, then it becomes some sort of pyramid (?). I was once able to do it and on the search for an instruction for this model, I came upon your site. just googled "origami forum", w/o the quotes.

so, can anyone please help me? I'll go on trying meanwhile...

edit: sorry, just found the sticky post with the links. I can't look at every single model right now, gotta go to work now. so, in the meantime, if you find anything: please post it!

edit 2: oh, and some of those sticky links don't work anymore...

Sounds like the Sonobe Unit.

I think you might be thinking of the "spike ball". Is this what you were thinking of? It's one of my favorites for folding on bus rides since it's so simple.

Maybe a Sonobe Unit variation. Does it look like any of these: http://www.fortunecity.com/meltingpot/a ... _unit.html

I remembered it after all...
you never turn the paper over, you only fold on one side. first, you fold it in half, along the sides, so you have 2 rectangles. then again, so you now have 4 squares. then you fold 2 sides to the middle, so you have 8 rectangles... from here I'm blank as how to explain it. but you go on folding until you have 2 isoscele triangles that together form a diamond shape. and if you have 3 of them, they can be joined together to form a 6sided "double pyramid" (for lack of a better expression)... 6 can make a cube, and 12 make this spiky ball I mentioned in the OP...

And you are sure it is not the Sonobe Unit?
