How did they do that??

[Frank]

Ever see a Lego creation and wonder "How did they do that?"
Happens to me all the time but then I'm a relative amateur.
I'd like folks to share their "How did they do that?" moments,
with or without solutions. I'll start the ball rolling:

It's round! How did they do that? A zillion hinge pieces? I dunno.

I think it is made with normal 1 X 2s.
They do have some flex in them...

What do the rest of you think?

Yes, it's 1x2's and they flex quite a bit. Then the pillers are pretty straight.

I'll echo it: It's definitely 1x2's. A lot of 1x2's.

To get even more flex, try using a pattern of 1x3's and 1x1 round bricks. (A 1x1 round above and below the 1x3 in the middle stud..)

My favourite example of this technique (The 1x2 design,) is Adrian's tribunal engines:

Here's another example. Could be a big wall of 1x2's but here's
another possibility: Cover a baseplate with tiles. If you use
narrow tiles aligned the same way you could probably flex it
a fair bit, concave or convex.

Quiet here lately...

This looks to be an example of the "bend it into a circle" method
on an enormous scale.
I came across this monster ferris wheel

then scoured the web and brickshelf looking for close-ups and
eventually found this

Looks like the outer ring of this beast consists of a mile or so
of 1xN beams and plates, studs on the side, bent into a circle.
You can see what looks like two motors with drive wheels
pressed against the ring.

Hey , check out this piano, I tried to put this thing together but couldn't figure out how to support they keyboard in the frame. The frame and the keys themselves weren't a problem but Connecting them was.
