In some parts of the world, stairs can wind around and abruptly take you from a run down area to a very modern, new looking place.
The old and the new often exist side by side.
I like stairs, I guess because sometimes you never know what will come into view as you climb them.
(Two quick notes – I added two more versions of the new animated jigsaw puzzle from yesterday – one easier, and one harder.
The other note is that you should check out JC Ayer’s hand made wooden jigsaw puzzles.)

Easy   Medium   Hard   Tough
