A test of a new kind of picture I would like to start making sometimes. 
Easy enough to not need answers provided.

For this one, a difference between two pictures.

Comments welcome:

Got to ask. Is it just my eyes or is the only 3D thing the block on the right?
Because somehow I'm not seeing anything else as 3D, with any depth. Like I said,
maybe it's my 3D visual interpretation messing up.

Sorry if I'm spoiling the puzzle already!

It's not a 3d picture for once. There are two similar images and you 
have to spot the differences.

Yes, there must be three. I can see two and I always miss one.

Good idea for a game. :)

I /might/ see a third difference, but am not sure if it is correct... 
Hmm, it is a very subtle one if it is true ;-)

I was sure the X block was a hint to do cross-eyed 3D! And it really makes for 3
differences that way.

I suggest people give that a look anyhow.

You managed to make 59112 ;)

But yeah, they can be grouped into three distinct sets -- one of which
does not follow the usual pattern of common "spot the difference" image
pairs.

That's very nice   :)
I would love to see a whole lot more of these puzzles.
It would be one more thing to show my son that's not some "anonymously" coded
video game.

{Though Monsters Ate My Birthday Cake (MAMBC) really is a very good game.}

I do have a question about real wooden blocks.   The ones I have seen up close
have a very interesting scalloped grooving where the background of the letters
and numbers are "differenced" out.   And the internal edges where that grooving
begins and ends is _sharp_ .   It's not pressed in, and if it's cut, I don't see
how.

I wondering how they do it!

How true. I had to rotate the image 180° to spot it. (A handy hint when 
looking at images you want to inspect closely.)

Too subtle for this group, I'm afraid. :-)

I tried but the image is too large for me to get it to work.

My guess would be multi-pass milling with a very fine milling bit for
the final pass.

The only alternative I can think of would be to produce the faces of the
cubes (the "frames" and letters) as separate sheets of wood, and glue
them onto the cubes; in that case the grooved pattern could also serve a
technical purpose, namely to improve the bonding.

Maybe I should use, a difference between two scenes?

My eyes are too old to be able to do that anymore.

As far as I can tell, the differences have nothing to do with 3D.

Found 3 in "b".
Not sure I have all 3's from "c" picture, unless 3 is all. Wouldn't want to be
timed on this anyway. Makes me feel slow.

Was trying to make 2 in "b", with 1 more not provable.

Hmmmm. I'm sure I found 3 things that would be different, aside from the actual
view being changed.
One being a letter, another a number, and I'll leave the 3rd for people to keep
guessing.

I've found 4 errors by now (again aside from the difference in
perspective), presuming the two cubes on the right are supposed to have
the numbers 1 to 6 on them and satisfy the typical convention for the
arrangement of the numbers.

Plus one more error if the letters "SJS" are supposed to be part of the
scene ;)

Then again, no -- they obviously don't follow the typical convention. So
back to 3 errors.

Found the 3 differences, 2 just jumped at me, and the last eluded me for 
a time. Nice trick in that last one.
