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.
