I've just finished another joint project with Daniel Shiu.
This time it's Escher's "Ascending and Descending". You can
find it at
http://www.lipsons.pwp.blueyonder.co.uk/escher/ascending.html
I haven't included any detail or "how we did it" pictures yet,
but I'll try to put them up in another day or two.
LMKWYT.

Two words: Very cool.
How long does it take you guys to put something like that together?
How much work do you have to do on paper?
(I'm just full of questions, aren't I?)

As always, great job!
Could we please some pictures from other angles to reveal some of the secrets.

Um wow. I am looking at the picture, following the lines, and I can't
figure out how you did it. Obviously both you and Daniel really study
Escher's work and do a lot of trial and error before getting the finished
product. Very impressive.

Jeez, looking at that thing is making my brain hurt.
Nice work!

Please more pics of this! It's obsessing to try to figure out how you did
it! Even if i'm certain to have fing it, I want to see it so my eyes will
finally believe it!
Amazing job guys! Keep it up!

Wow! That's brilliant. I'm trying to figure out how it's done. Are the
stairs on the right, coming up towards the nearest corner, actually sloping
down? Or is there a break in the upper corner, with the edges hidden by
those two figures passing each other?

Beautiful! and maddening!
How in the heck did you do that? You're getting better. The last one I
could kind of tell from the picture how you did it, at least the columns.
This one totally baffles me. The central hole between the stairwells is
definitely not rectangular, the inner wall is like 8 studs on the upper left
and more like 14 on the lower right, but every corner looks like a right
angle. Not to mention, of course, how the stairs keep going up. I suspect
that when you show it from the side we'll see a spiral staircase that goes
up and then just ends, suspended in space, but when seen from the correct
perspective it perfectly lines up with the stairs below, but if that's what
you did it is so masterful that you cannot tell.
A couple of other details: I really like the upper-left roof. I'll have to
try that technique of using 45 and 33 degree slopes sometime. Also, a nice
detail is the gray fence on the lower right. How did you attach the 2x2
fenceposts to the 1xn fences with the studs half-offset?
This model, btw, really belongs in a museum. I could totally see in a
museum of science and technology having a display on perspective and optical
illusions. You could have this model sitting there and people could walk
around it, but then have a little scope where you look through from exactly
this perspective and see the illusion. Being in Lego is a big plus because
those types of museums usually try to make themselves very kid-accessible,
so using a toy as your medium is ideal.

I love these Escher sculptures! Make more please.
I suspect the secret to this one is all in the upper right corner.
A quick attempt to approximate it with LDRAW ends up like this.

Great! Keep going! I really like your realizations. My only beef is that now
that you've made the easy ones <g> it's a much harder job for anyone else
wanting to follow-up. I have been _thinking_ about the stairs, but not even
come close to touching a piece of real Lego. Back to the Escher book to see
what's left.
BTW, I can see where the studs suddenly are getting a bit smaller,
indicating a gap in the shortest (back) stair. How difficult was it to find
the correct camera angle? Did you experiment with just the stairs first? If
so, live or with virtual bricks?
Once again, Great Modelling!

AH HA!!! You've found it! I should have seen that, too, because I was
counting studs, but it totally slipped past me.

Rats! That means I modeled the gap in the wrong spot. Oh well,
Back to the drawing board.

Heh, that's how I found it-- counted studs as best I could, noticing that
that wall was rather shorter than it should be :) But remarkably well done!
It took me a while of searching desperately before I broke down and started
counting studs. I never noticed the stud size discrepancy, though. If only
I'd thought of that right off! :)

I was afraid that the minifig size discrepancy would give it
away! But I'm glad we managed to keep you occupied for a
bit ;-)

Yeah, the minifig size discrepancy was what gave it away for me - but it did
take close observation to notice. Well done!

Stevn Combs asked if I would let BimP publish the secret;
you can find some spoiler pictures and a summary of the
building process there, at http://www.bricksinmypocket.org,
under "Models". Enjoy!
I'll add to my own web page in a week or so.

Not as exciting as all that, I'm afraid. We just used a bunch
of white 1x2 half-stud spacer plates.

Well, I have to admit that we got a bit lazy about colours
on the walls that aren't visible in the picture, so it looks
a bit scraggy from the back (but quite structurally complete).
Nevertheless, a friend who is a mathematics teacher at a
local school has asked if they can put it on display for
a while. The big problem is whether we can get it out of
my attic in one piece...

We thought about the picture on and off for quite a while.
I'm not sure how long, because we've been drifting back
and forth from one Escher picture to another trying to
decide which to do next. In fact, I'd already started a
mock-up for another one, and some preliminary programming
work for yet another (no, I'm not saying which they are -
we may never solve the problems and get them finished).
Anyway, once work started on this properly and we'd
figured out the general scheme, the only paper preparation
was sketching out a rough plan view on a sheet of paper.
After that, building took several evenings spread over
two or three weeks - we had to backtrack quite a lot,
and there were several changes in the colour scheme as
the building progressed.
So it wasn't a _huge_ project - at leazt, not in comparison
with "Balcony", which kept us busy for more than three
months...
